Direct Access (DAX) can be used on memory-backed block devices.

If the block device supports DAX and the filesystem supports DAX,

on this option will compile in support for DAX; you will need to

mount the filesystem using the -o dax option.

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.

|
|

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.
