Hi Linus,

Not sure you'll be OK with what I've done or not but I pulled in a
1-liner "slab/urgent" fix that Pekka staged a couple months ago.  I've
made it available through a signed tag in the linux-dm.git tree.  My
reasoning on why this is OK is it regularly impacts DM and Pekka already
Signed-off on it (as did other mm developers).  I'm pretty sure Pekka
just forgot to follow through preparing a pull request for 3.15.

If you'd rather take this direct from Pekka (or wait for Andrew to pick
up the same patch which David just sent him) that is fine by me, I just
want the issue fixed.

The following changes since commit 048e5a07f282c57815b3901d4a68a77fa131ce0a:

  dm cache metadata: do not allow the data block size to change (2014-07-15 14:07:50 -0400)

Please pull, thanks.


This fixes the broken duplicate slab name check in
kmem_cache_sanity_check() that has been repeatedly reported (as recently
as today against Fedora rawhide).  Pekka seemed to have it staged for a
late 3.15-rc in his 'slab/urgent' branch but never sent a pull request,
