  43           Direct Access (DAX) can be used on memory-backed block devices.
  44           If the block device supports DAX and the filesystem supports DAX,
  45           then you can avoid using the pagecache to buffer I/Os.  Turning
  46           on this option will compile in support for DAX; you will need to
  47           mount the filesystem using the -o dax option.
  48

 126           Tmpfs is a file system which keeps all files in virtual memory.
 127
 128           Everything in tmpfs is temporary in the sense that no files will be
 129           created on your hard drive. The files live in memory and swap
 130           space. If you unmount a tmpfs instance, everything stored therein is
 131           lost.

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

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