63 This option enables standard file locking support, required
64 for filesystems like NFS and for the flock() system

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