-+	help
-+	  Saying Y here includes support for SquashFs 2.0 (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 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.

-+	  allocates memory.  This is only intended for memory constrained
-+	  systems.

-+
-+config SQUASHFS_FRAGMENT_CACHE_SIZE
-+	int "Number of fragments cached" if SQUASHFS_EMBEDDED
-+	depends on SQUASHFS
-+	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.
