Subject: PULL REQUEST md updates for 3.2


Hi Linus,
 please pull following md updates for 3.2
 Most of them are just code cleanups and minor bug fixes.
 There is one fix for a RAID5 bug which could lead to data corruption
 due to reading old data from a device that is marked as faulty.  It is a
 small race as the drive is normally removed from consideration very soon
 after being marked faulty.  This patch is flagged for inclusion in -stable.
 It is commit 355840e7a7e56bb.

 This series conflicts with the patch
    block: remove support for bio remapping from ->make_request
 from  Christoph Hellwig in the block tree.
 That patch changes 'make_request' functions to return void.  I have patches
 which change the types of args to some of those functions from a typedef to
 a 'struct XXX'.
 The conflict is fairly easy to resolve ("wiggle" does it perfectly), or you
 could pull my "for-next" branch (85d7a4e56fbe09c1) instead which includes
 block-3.1 and resolves the conflict.

Thanks,
NeilBrown
