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