51 help
52 Direct Access (DAX) can be used on memory-backed block devices.
53 If the block device supports DAX and the filesystem supports DAX,
54 then you can avoid using the pagecache to buffer I/Os. Turning
55 on this option will compile in support for DAX; you will need to
56 mount the filesystem using the -o dax option.
57
58 If you do not have a block device that is capable of using this,
59 or if unsure, say N. Saying Y will increase the size of the kernel
60 by about 5kB.

160 Tmpfs is a file system which keeps all files in virtual memory.
161
162 Everything in tmpfs is temporary in the sense that no files will be
163 created on your hard drive. The files live in memory and swap
164 space. If you unmount a tmpfs instance, everything stored therein is
165 lost.
166
167 See <file:Documentation/filesystems/tmpfs.txt> for details.

175 POSIX Access Control Lists (ACLs) support additional access rights
176 for users and groups beyond the standard owner/group/world scheme,
177 and this option selects support for ACLs specifically for tmpfs
178 filesystems.
179
180 If you've selected TMPFS, it's possible that you'll also need
181 this option as there are a number of Linux distros that require
182 POSIX ACL support under /dev for certain features to work properly.
183 For example, some distros need this feature for ALSA-related /dev
184 files for sound to work properly. In short, if you're not sure,
185 say Y.
