114    help
115      Tmpfs is a file system which keeps all files in virtual memory.
116
117      Everything in tmpfs is temporary in the sense that no files will be
118      created on your hard drive. The files live in memory and swap
119      space. If you unmount a tmpfs instance, everything stored therein is
120      lost.
121
122      See <file:Documentation/filesystems/tmpfs.txt> for details.

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

145config TMPFS_XATTR

150      Extended attributes are name:value pairs associated with inodes by
151      the kernel or by users (see the attr(5) manual page, or visit
152      <http://acl.bestbits.at/> for details).
153
154      Currently this enables support for the trusted.* and
155      security.* namespaces.
156
157      You need this for POSIX ACL support on tmpfs.
