The -+ * "next" pointer of the last BRANCH in a choice points to the -+ * thing following the whole choice. This is also where the -+ * final "next" pointer of each individual branch points; each -+ * branch starts with the operand node of a BRANCH node. -+ * -+ * BACK Normal "next" pointers all implicitly point forward; BACK -+ * exists to make loop structures possible. -+ * -+ * STAR,PLUS '?', and complex '*' and '+', are implemented as circular -+ * BRANCH structures using BACK.

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. -+ -+ -+ -+Copyright (C) 2004, 2005 Markus Klotzbuecher <mk@creamnet.de> -+ -+This program is free software; you can redistribute it and/or -+modify it under the terms of the GNU General Public License -+as published by the Free Software Foundation; either version -+2 of the License, or (at your option) any later version. -+ -+ ---- /dev/null -+++ b/fs/mini_fo/RELEASE_NOTES -@@ -0,0 +1,111 @@ -+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. ---- /dev/null -+++ b/fs/mini_fo/state.c -@@ -0,0 +1,620 @@ -+/* -+ * Copyright (C) 2005 Markus Klotzbuecher <mk@creamnet.de> -+ * -+ * This program is free software;

If the flag is checked, then spi_async() -must fail immediately. - -The current runtime API looks like this: -spi_async(struct spi_device*, struct spi_message*); -spi_sync(struct spi_device*, struct spi_message*); - -The API needs to be extended to this: -spi_async(struct spi_device*, struct spi_message*) -spi_sync(struct spi_device*, struct spi_message*) -spi_bus_lock(struct spi_master*) /* although struct spi_device* might -be easier */ -spi_bus_unlock(struct spi_master*) -spi_async_locked(struct spi_device*, struct spi_message*) -spi_sync_locked(struct spi_device*, struct spi_message*) - -Drivers can only call the last two if they already hold the spi_master_lock(). - -spi_bus_lock() obtains the mutex, obtains the spin lock, sets the -flag, and releases the spin lock before returning. It doesn't even -need to sleep while waiting for "in-flight" spi_transactions to -complete because its purpose is to guarantee no additional -transactions are added. It does not guarantee that the bus is idle. - -spi_bus_unlock() clears the flag and releases the mutex, which will -wake up any waiters. - -The difference between spi_async() and spi_async_locked() is that the -locked version bypasses the check of the lock flag. Both versions -need to obtain the spinlock. - -The difference between spi_sync() and spi_sync_locked() is that -spi_sync() must hold the mutex while enqueuing a new transfer. -spi_sync_locked() doesn't because the mutex is already held. Note -however that spi_sync must *not* continue to hold the mutex while -waiting for the transfer to complete, otherwise only one transfer -could be queued up at a time! - -Almost no code needs to be written. The current spi_async() and -spi_sync() can probably be renamed to __spi_async() and __spi_sync() -so that spi_async(), spi_sync(), spi_async_locked() and -spi_sync_locked() can just become wrappers around the common code. - -spi_sync() is protected by a mutex because it can sleep -spi_async() needs to be protected with a flag and a spinlock because -it can be called atomically and must not sleep - -Signed-off-by: Ernst Schwab <eschwab@online.de> -[grant.likely@secretlab.ca: use spin_lock_irqsave()] -Signed-off-by: Grant Likely <grant.likely@secretlab.ca> -Tested-by: Matt Fleming <matt@console-pimps.org> -Tested-by: Antonio Ospite <ospite@studenti.unina.it> ---- - drivers/spi/spi.c | 225 ++++++++++++++++++++++++++++++++++++++++------- - include/linux/spi/spi.h | 12 +++ - 2 files changed, 204 insertions(+), 33 deletions(-) - ---- a/drivers/spi/spi.c -+++ b/drivers/spi/spi.c -@@ -527,6 +527,10 @@ int spi_register_master(struct spi_maste - dynamic = 1; - } - -+ spin_lock_init(&master->bus_lock_spinlock); -+ mutex_init(&master->bus_lock_mutex); -+ master->bus_lock_flag = 0; -+ - /* register the device, then userspace will see it. - * registration fails if the bus ID is in use. - */ -@@ -666,6 +670,35 @@ int spi_setup(struct spi_device *spi) - } - EXPORT_SYMBOL_GPL(spi_setup); - -+static int __spi_async(struct spi_device *spi, struct spi_message *message) -+{ -+ struct spi_master *master = spi->master; -+ -+ /* Half-duplex links include original MicroWire, and ones with -+ * only one data pin like SPI_3WIRE (switches direction) or where -+ * either MOSI or MISO is missing.
