Paolo Bonzini 398205b839 blk_mq: call preempt_disable/enable in blk_mq_run_hw_queue, and only if needed ... preempt_disable/enable surrounds every call to blk_mq_run_hw_queue, except the one in blk-flush.c. In fact that one is always asynchronous, and it does not need smp_processor_id(). We can do the same for all other calls, avoiding preempt_disable when async is true. This avoids peppering blk-mq.c with preemption-disabled regions.
