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"
