This option enables standard file locking support, required

for filesystems like NFS and for the flock() system

call. Disabling this option saves about 11k.

bool "Tmpfs virtual memory file system support (former shm fs)"

depends on SHMEM

help

Tmpfs is a file system which keeps all files in virtual memory.

Everything in tmpfs is temporary in the sense that no files will be

created on your hard drive. The files live in memory and swap

space. If you unmount a tmpfs instance, everything stored therein is

lost.

See <file:Documentation/filesystems/tmpfs.txt> for details.

config TMPFS_POSIX_ACL

select TMPFS_XATTR

select GENERIC_ACL

help

POSIX Access Control Lists (ACLs) support additional access rights

for users and groups beyond the standard owner/group/world scheme,

and this option selects support for ACLs specifically for tmpfs

filesystems.

If you've selected TMPFS, it's possible that you'll also need

this option as there are a number of Linux distros that require

POSIX ACL support under /dev for certain features to work properly.

For example, some distros need this feature for ALSA-related /dev

files for sound to work properly. In short, if you're not sure,

say Y.

To learn more about Access Control Lists, visit the POSIX ACLs for

Linux website <http://acl.bestbits.at/>.

config TMPFS_XATTR

bool "Tmpfs extended attributes"

depends on TMPFS

default n

help

Extended attributes are name:value pairs associated with inodes by

the kernel or by users (see the attr(5) manual page, or visit

<http://acl.bestbits.at/> for details).

Currently this enables support for the trusted.* and

security.* namespaces.

You need this for POSIX ACL support on tmpfs.

If unsure, say N.
