[dm-devel] [PATCH for-next 00/20] dm: current patches queued in linux-dm.git for-next

[Mike Snitzer]

I've pushed these changes to linux-dm.git's for-next branch.  The
first 2 will likely still go to Linus for 3.13.  But the others are
all for 3.14.  Any of these patches can be modified/rebased/etc so
please shout if you see something you don't like.  Also please shout
if there is a patch you don't see queued but feel it should be (Hannes
I haven't gotten to your dm-mpath invalid paths patch yet, sorry).

I put a lot of work into fixing the thinp target's handling of
-ENOSPC.  I'd appreciate it if reviewers interested in this area would
put particular focus on patch 18: "dm thin: fix pool_preresume resize
with heavy IO races".

Happy Holidays,
Mike
