 39           Direct Access (DAX) can be used on memory-backed block devices.
 40           If the block device supports DAX and the filesystem supports DAX,
 41           then you can avoid using the pagecache to buffer I/Os.  Turning
 42           on this option will compile in support for DAX; you will need to
 43           mount the filesystem using the -o dax option.
 44 
 45           If you do not have a block device that is capable of using this,

130           Tmpfs is a file system which keeps all files in virtual memory.
131 
132           Everything in tmpfs is temporary in the sense that no files will be
133           created on your hard drive. The files live in memory and swap
134           space. If you unmount a tmpfs instance, everything stored therein is
135           lost.

145           POSIX Access Control Lists (ACLs) support additional access rights
146           for users and groups beyond the standard owner/group/world scheme,
147           and this option selects support for ACLs specifically for tmpfs
148           filesystems.
149 
150           If you've selected TMPFS, it's possible that you'll also need
151           this option as there are a number of Linux distros that require
152           POSIX ACL support under /dev for certain features to work properly.
153           For example, some distros need this feature for ALSA-related /dev
154           files for sound to work properly.  In short, if you're not sure,
155           say Y.
156

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