[dm-devel] [PATCH 00/24] dm cache: proposed changes for v3.13 merge

[Mike Snitzer]

The following patches have been published to the 'for-next' branch of
the device-mapper git repository:
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git

The patches marked as RFC (19-24) could use the most review.  But all
review would be appreciated.

Thanks,
Mike
