102 bool "Tmpfs virtual memory file system support (former shm fs)"
105 Tmpfs is a file system which keeps all files in virtual memory.
107 Everything in tmpfs is temporary in the sense that no files will be
108 created on your hard drive. The files live in memory and swap
109 space. If you unmount a tmpfs instance, everything stored therein is
112 See <file:Documentation/filesystems/tmpfs.txt> for details.
114 config TMPFS_POSIX_ACL
115 bool "Tmpfs POSIX Access Control Lists"
120 POSIX Access Control Lists (ACLs) support additional access rights
121 for users and groups beyond the standard owner/group/world scheme,
122 and this option selects support for ACLs specifically for tmpfs
125 If you've selected TMPFS, it's possible that you'll also need
126 this option as there are a number of Linux distros that require
127 POSIX ACL support under /dev for certain features to work properly.
128 For example, some distros need this feature for ALSA-related /dev
129 files for sound to work properly. In short, if you're not sure,
132 To learn more about Access Control Lists, visit the POSIX ACLs for
133 Linux website <http://acl.bestbits.at/>.
136 bool "Tmpfs extended attributes"
140 Extended attributes are name:value pairs associated with inodes by
141 the kernel or by users (see the attr(5) manual page, or visit
142 <http://acl.bestbits.at/> for details).
144 Currently this enables support for the trusted.* and
145 security.* namespaces.
147 You need this for POSIX ACL support on tmpfs.
