61 This option enables standard file locking support, required
62 for filesystems like NFS and for the flock() system
63 call. Disabling this option saves about 11k.

108 bool "Tmpfs virtual memory file system support (former shm fs)"
111 Tmpfs is a file system which keeps all files in virtual memory.
113 Everything in tmpfs is temporary in the sense that no files will be
114 created on your hard drive. The files live in memory and swap
115 space. If you unmount a tmpfs instance, everything stored therein is
118 See <file:Documentation/filesystems/tmpfs.txt> for details.

121 bool "Tmpfs POSIX Access Control Lists"
126 POSIX Access Control Lists (ACLs) support additional access rights
127 for users and groups beyond the standard owner/group/world scheme,
128 and this option selects support for ACLs specifically for tmpfs
131 If you've selected TMPFS, it's possible that you'll also need
132 this option as there are a number of Linux distros that require
133 POSIX ACL support under /dev for certain features to work properly.
134 For example, some distros need this feature for ALSA-related /dev
135 files for sound to work properly. In short, if you're not sure,
138 To learn more about Access Control Lists, visit the POSIX ACLs for
139 Linux website <http://acl.bestbits.at/>.
142 bool "Tmpfs extended attributes"
146 Extended attributes are name:value pairs associated with inodes by
147 the kernel or by users (see the attr(5) manual page, or visit
148 <http://acl.bestbits.at/> for details).
150 Currently this enables support for the trusted.* and
151 security.* namespaces.
153 You need this for POSIX ACL support on tmpfs.
