dm cache: lift common migration preparation code to alloc_migration() (2017-11-10 15:45:07 -0500)
Please pull, thanks!
Mike
----------------------------------------------------------------
- A few conversions from atomic_t to ref_count_t
- A DM core fix for a race during device destruction that could result
in a BUG_ON.
- A stable@ fix for a DM cache race condition that could lead to data
corruption when operating in writeback mode (writethrough is default)
- Various DM cache cleanups and improvements
- Add DAX support to the DM log-writes target
- A fix for the DM zoned target's ability to deal with the last zone of
the drive being smaller than all others.
- A stable@ DM crypt and DM integrity fix for a negative check that was
to restrictive (prevented slab debug with XFS ontop of DM crypt from
working).
- A DM raid target fix for a panic that can occur when forcing a raid to
sync.
