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

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

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

154 Currently this enables support for the trusted.* and
