118	help
119	  Tmpfs is a file system which keeps all files in virtual memory.
120
121	  Everything in tmpfs is temporary in the sense that no files will be
122	  created on your hard drive. The files live in memory and swap
123	  space. If you unmount a tmpfs instance, everything stored therein is
124	  lost.
125
126	  See <file:Documentation/filesystems/tmpfs.txt> for details.

133	help
134	  POSIX Access Control Lists (ACLs) support additional access rights
135	  for users and groups beyond the standard owner/group/world scheme,
136	  and this option selects support for ACLs specifically for tmpfs
137	  filesystems.
138
139	  If you've selected TMPFS, it's possible that you'll also need
140	  this option as there are a number of Linux distros that require
141	  POSIX ACL support under /dev for certain features to work properly.
142	  For example, some distros need this feature for ALSA-related /dev
143	  files for sound to work properly.  In short, if you're not sure,
144	  say Y.
145
146	  To learn more about Access Control Lists, visit the POSIX ACLs for
147	  Linux website <http://acl.bestbits.at/>.

154	  Extended attributes are name:value pairs associated with inodes by
155	  the kernel or by users (see the attr(5) manual page, or visit
156	  <http://acl.bestbits.at/> for details).
157
158	  Currently this enables support for the trusted.* and
159	  security.* namespaces.
160
161	  You need this for POSIX ACL support on tmpfs.
