43 help
44 Direct Access (DAX) can be used on memory-backed block devices.
45 If the block device supports DAX and the filesystem supports DAX,
46 then you can avoid using the pagecache to buffer I/Os. Turning
47 on this option will compile in support for DAX; you will need to
48 mount the filesystem using the -o dax option.
49
50 If you do not have a block device that is capable of using this,
51 or if unsure, say N. Saying Y will increase the size of the kernel
52 by about 5kB.

150 Tmpfs is a file system which keeps all files in virtual memory.
151
152 Everything in tmpfs is temporary in the sense that no files will be
153 created on your hard drive. The files live in memory and swap
154 space. If you unmount a tmpfs instance, everything stored therein is
155 lost.
156
157 See <file:Documentation/filesystems/tmpfs.txt> for details.

165 POSIX Access Control Lists (ACLs) support additional access rights
166 for users and groups beyond the standard owner/group/world scheme,
167 and this option selects support for ACLs specifically for tmpfs
168 filesystems.
169
170 If you've selected TMPFS, it's possible that you'll also need
171 this option as there are a number of Linux distros that require
172 POSIX ACL support under /dev for certain features to work properly.
173 For example, some distros need this feature for ALSA-related /dev
174 files for sound to work properly. In short, if you're not sure,
175 say Y.
