In linux kernel since version 3.1 (release Date: 2011-10-24)
dm-cache attempts to improve performance of a block device by
moving frequently used data to a smaller, higher performance
device. Different 'policy' plugins can be used to change the
algorithms used to select which blocks are promoted, demoted,
cleaned etc. It supports writeback and writethrough modes.
