Direct Access (DAX) can be used on memory-backed block devices.
|
|
If the block device supports DAX and the filesystem supports DAX,
|
|
then you can avoid using the pagecache to buffer I/Os. Turning
|
|
on this option will compile in support for DAX; you will need to
|
|
mount the filesystem using the -o dax option.
|
|
|
|
If you do not have a block device that is capable of using this,
|
|
or if unsure, say N. Saying Y will increase the size of the kernel
|

by about 5kB.

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.

|
|
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.
|
|
|
|

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

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

Currently this enables support for the trusted.* and

You need this for POSIX ACL support on tmpfs.
