-+ select ZLIB_INFLATE
-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+config SQUASHFS_FRAGMENT_CACHE_SIZE
-+ int "Number of fragments cached" if SQUASHFS_EMBEDDED

-+ default "3"
-+ help
-+ By default SquashFS caches the last 3 fragments read from
-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.
-+
-+config SQUASHFS_VMALLOC
-+ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED
-+ depends on SQUASHFS
-+ default n
-+ help
-+ By default SquashFS uses kmalloc to obtain fragment cache memory.
-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ * that regcomp() supplies a regmust only if the r.e. contains something

-+ * Structure for regexp "program". This is essentially a linear encoding
-+ * of a nondeterministic finite-state machine (aka syntax charts or
-+ * "railroad normal form" in parsing technology). Each node is an opcode
-+ * plus a "next" pointer, possibly plus an operand. "Next" pointers of
-+ * all nodes except BRANCH implement concatenation; a "next" pointer with
-+ * a BRANCH on both ends of it is connecting two alternatives. (Here we
-+ * have one of the subtle syntax dependencies: an individual BRANCH (as
-+ * opposed to a collection of them) is never concatenated with anything
-+ * because of operator precedence.) The operand of some types of node is
-+ * a literal string; for others, it is a node leading into a sub-FSM. In
-+ * particular, the operand of a BRANCH node is the first node of the branch.
-+ * (NB this is *not* a tree structure: the tail of the branch connects
-+ * to the thing following the set of BRANCHes.) The opcodes are:

-+ *
-+ * The first version was written by Martin Devera, <devik@cdi.cz>

-+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
-+ * - Fix "Dead-loop on netdevice imq"-issue
-+ * Marcel Sebek <sebek64@post.cz>
-+ * - Update to 2.6.2-rc1
-+ *
-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
-+ * the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with
-+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ * I didn't forget anybody). I apologize again for my lack of time.

-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+will use a storage directory called "sto-<base_dir_name>" in $STO_DIR,
-+and mount point "mini_fo-<base_dir_dir>" in $MNT_DIR.
-+
-+Options:
-+ -s <suffix>
-+ add given suffix to storage directory and the mount
-+ point. This is usefull for overlaying one base directory
-+ several times and avoiding conflicts with storage directory
-+ names and mount points.
-+
-+ -d <sto_dir_dir>
-+ change the directory in which the storage directory will be
-+ created (default is currently "$STO_DIR".

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release: mini_fo-0.6.1 (v0-6-1)
-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.
