106 bool "Tmpfs virtual memory file system support (former shm fs)"
109 Tmpfs is a file system which keeps all files in virtual memory.
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
116 See <file:Documentation/filesystems/tmpfs.txt> for details.

119 bool "Tmpfs POSIX Access Control Lists"
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
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,
136 To learn more about Access Control Lists, visit the POSIX ACLs for
137 Linux website <http://acl.bestbits.at/>.
140 bool "Tmpfs extended attributes"
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).
148 Currently this enables support for the trusted.* and
149 security.* namespaces.
151 You need this for POSIX ACL support on tmpfs.
