105	help
106	  Tmpfs is a file system which keeps all files in virtual memory.
107
108	  Everything in tmpfs is temporary in the sense that no files will be
109	  created on your hard drive. The files live in memory and swap
110	  space. If you unmount a tmpfs instance, everything stored therein is
111	  lost.
112
113	  See <file:Documentation/filesystems/tmpfs.txt> for details.

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

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