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.

48 If you do not have a block device that is capable of using this,
49 or if unsure, say N. Saying Y will increase the size of the kernel

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

139 created on your hard drive. The files live in memory and swap
140 space. If you unmount a tmpfs instance, everything stored therein is
141 lost.
