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"
* 'for-linus' of git://git.kernel.dk/linux-block:
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
