Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "Small collection of fixes for 3.14-rc. It contains:

   - Three minor update to blk-mq from Christoph.

   - Reduce number of unaligned (< 4kb) in-flight writes on mtip32xx to
     two.  From Micron.

   - Make the blk-mq CPU notify spinlock raw, since it can't be a
     sleeper spinlock on RT.  From Mike Galbraith.

   - Drop now bogus BUG_ON() for bio iteration with blk integrity.  From
     Nic Bellinger.

   - Properly propagate the SYNC flag on requests. From Shaohua"

  blk-mq: add REQ_SYNC early
  rt,blk,mq: Make blk_mq_cpu_notify_lock a raw spinlock
  bio-integrity: Drop bio_integrity_verify BUG_ON in post bip->bip_iter world
  blk-mq: support partial I/O completions
  blk-mq: merge blk_mq_insert_request and blk_mq_run_request
  blk-mq: remove blk_mq_alloc_rq
  mtip32xx: Reduce the number of unaligned writes to 2
