Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull one last block fix from Jens Axboe: "We've had an issue with scsi-mq where probing takes forever. This was bisected down to the percpu changes for blk_mq_queue_enter(), and the fact we now suffer an RCU grace period when killing a queue. SCSI creates and destroys tons of queues, so this let to 10s of seconds of stalls at boot for some. Tejun has a real fix for this, but it's too involved for 3.17. So this is a temporary workaround to expedite the queue killing until we can fold in the real fix for 3.18 when that merge window opens" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq, percpu_ref: implement a kludge for SCSI blk-mq stall during probe
