53 bool "Enable POSIX file locking API" if EXPERT
56 This option enables standard file locking support, required
57 for filesystems like NFS and for the flock() system
58 call. Disabling this option saves about 11k.

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