42 Direct Access (DAX) can be used on memory-backed block devices.
43 If the block device supports DAX and the filesystem supports DAX,
44 then you can avoid using the pagecache to buffer I/Os. Turning
45 on this option will compile in support for DAX; you will need to
46 mount the filesystem using the -o dax option.

143 Tmpfs is a file system which keeps all files in virtual memory.

145 Everything in tmpfs is temporary in the sense that no files will be
146 created on your hard drive. The files live in memory and swap
147 space. If you unmount a tmpfs instance, everything stored therein is
148 lost.
