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

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.
