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
