config SQUASHFS
	tristate "SquashFS 3.1 - Squashed file system support"
	select ZLIB_INFLATE
	help
	  Saying Y here includes support for SquashFS 3.1 (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 3.1 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.

config SQUASHFS_EMBEDDED

	bool "Additional options for memory-constrained systems" 
	depends on SQUASHFS
	default n
	help
	  Saying Y here allows you to specify cache sizes and how Squashfs
	  allocates memory.  This is only intended for memory constrained
	  systems.

	  If unsure, say N.

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.

	  If unsure, say N.
