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.
