  40           Direct Access (DAX) can be used on memory-backed block devices.
  41           If the block device supports DAX and the filesystem supports DAX,
  42           then you can avoid using the pagecache to buffer I/Os.  Turning
  43           on this option will compile in support for DAX; you will need to
  44           mount the filesystem using the -o dax option.
  45
  46           If you do not have a block device that is capable of using this,
  47           or if unsure, say N.  Saying Y will increase the size of the kernel
  48           by about 5kB.

 114           Tmpfs is a file system which keeps all files in virtual memory.
 115
 116           Everything in tmpfs is temporary in the sense that no files will be
 117           created on your hard drive. The files live in memory and swap
 118           space. If you unmount a tmpfs instance, everything stored therein is
 119           lost.

 129           POSIX Access Control Lists (ACLs) support additional access rights
 130           for users and groups beyond the standard owner/group/world scheme,
 131           and this option selects support for ACLs specifically for tmpfs
 132           filesystems.
 133
 134           If you've selected TMPFS, it's possible that you'll also need
 135           this option as there are a number of Linux distros that require
 136           POSIX ACL support under /dev for certain features to work properly.
 137           For example, some distros need this feature for ALSA-related /dev
 138           files for sound to work properly.  In short, if you're not sure,
 139           say Y.
 140
