  	  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.

  	help

  	  POSIX Access Control Lists (ACLs) support additional access rights
  	  for users and groups beyond the standard owner/group/world scheme,
  	  and this option selects support for ACLs specifically for tmpfs
  	  filesystems.
  
  	  If you've selected TMPFS, it's possible that you'll also need
  	  this option as there are a number of Linux distros that require
  	  POSIX ACL support under /dev for certain features to work properly.
  	  For example, some distros need this feature for ALSA-related /dev
  	  files for sound to work properly.  In short, if you're not sure,
  	  say Y.

  
  	  To learn more about Access Control Lists, visit the POSIX ACLs for
  	  Linux website <http://acl.bestbits.at/>.

  	  <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.
