        help
          Tmpfs is a file system which keeps all files in virtual memory.

          Everything in tmpfs is temporary in the sense that no files will be
          created on your hard drive. The files live in memory and swap
          space. If you unmount a tmpfs instance, everything stored therein is
          lost.

          See <file:Documentation/filesystems/tmpfs.txt> for details.

          Extended attributes are name:value pairs associated with inodes by
          the kernel or by users (see the attr(5) manual page, or visit
          <http://acl.bestbits.at/> for details).

          Currently this enables support for the trusted.* and
          security.* namespaces.

          You need this for POSIX ACL support on tmpfs.

        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.

config SQUASHFS_EMBEDDED

        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.
