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.

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