  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,
  46           or if unsure, say N.  Saying Y will increase the size of the kernel

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

 147           POSIX Access Control Lists (ACLs) support additional access rights
 148           for users and groups beyond the standard owner/group/world scheme,
 149           and this option selects support for ACLs specifically for tmpfs
 150           filesystems.
 151
 152           If you've selected TMPFS, it's possible that you'll also need
 153           this option as there are a number of Linux distros that require
 154           POSIX ACL support under /dev for certain features to work properly.
 155           For example, some distros need this feature for ALSA-related /dev
 156           files for sound to work properly.  In short, if you're not sure,
 157           say Y.
 158
