++	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.
++
++	  If unsure, say N.

++	  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.
