 109          Tmpfs is a file system which keeps all files in virtual memory.
 110
 111          Everything in tmpfs is temporary in the sense that no files will be
 112          created on your hard drive. The files live in memory and swap
 113          space. If you unmount a tmpfs instance, everything stored therein is
 114          lost.
 115
 116          See <file:Documentation/filesystems/tmpfs.txt> for details.

 123        help
 124          POSIX Access Control Lists (ACLs) support additional access rights
 125          for users and groups beyond the standard owner/group/world scheme,
 126          and this option selects support for ACLs specifically for tmpfs
 127          filesystems.
 128
 129          If you've selected TMPFS, it's possible that you'll also need
 130          this option as there are a number of Linux distros that require
 131          POSIX ACL support under /dev for certain features to work properly.
 132          For example, some distros need this feature for ALSA-related /dev
 133          files for sound to work properly.  In short, if you're not sure,
 134          say Y.
 135

 137          Linux website <http://acl.bestbits.at/>.

 143        help
 144          Extended attributes are name:value pairs associated with inodes by
 145          the kernel or by users (see the attr(5) manual page, or visit
 146          <http://acl.bestbits.at/> for details).
 147
 148          Currently this enables support for the trusted.* and
 149          security.* namespaces.
 150
 151          You need this for POSIX ACL support on tmpfs.
