*	dm cache: policy change version from string to integer set	Mike Snitzer	2013-03-20	1	-2/+6
\| \| \| \| \| \| \| \| \| \|	Separate dm cache policy version string into 3 unsigned numbers corresponding to major, minor and patchlevel and store them at the end of the on-disk metadata so we know which version of the policy generated the hints in case a future version wants to use them differently.

*	dm cache: add mq policy	Joe Thornber	2013-03-01	1	-0/+1195
	A cache policy that uses a multiqueue ordered by recent hit count to select which blocks should be promoted and demoted. This is meant to be a general purpose policy. It prioritises reads over writes. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
