-+	  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

-+	  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/>.
-+
-+config TMPFS_XATTR
-+	bool "Tmpfs extended attributes"

-+	help
-+	  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
