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.

135
136	  If you've selected TMPFS, it's possible that you'll also need
137	  this option as there are a number of Linux distros that require
138	  POSIX ACL support under /dev for certain features to work properly.
