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

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

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