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

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

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