Now hctx->lock is only acquired when adding hctx->dispatch_wait to one wait queue, but not held when removing it from the wait queue. IO hang can be observed easily if SCHED RESTART is disabled, that means now RESTART exits just for fixing the issue in blk_mq_mark_tag_wait(). This patch fixes the issue by introducing hctx->dispatch_wait_lock and holding it for removing hctx->dispatch_wait in blk_mq_dispatch_wake(), since we need to avoid acquiring hctx->lock in irq context.

We never pass 'wait' as true to blk_mq_get_driver_tag(), and hence we never change '**hctx' as well. The last use of these went away with the flush cleanup, commit 0c2a6fe4. So cleanup the usage and remove the two extra parameters.

The actual goal of the function bfq_bfqq_may_idle is to tell whether it is better to perform device idling (more precisely: I/O-dispatch plugging) for the input bfq_queue, either to boost throughput or to preserve service guarantees. This commit improves the name of the function accordingly.

If - a bfq_queue Q preempts another queue, because one request of Q arrives in time, - but, after this preemption, Q is not the queue that is set in service, then Q->entity.service is set to 0 when Q is eventually set in service. But Q should have continued receiving service with its old budget (which is why preemption has occurred) and its old service. This commit addresses this issue by resetting service on queue real expiration.

For some bfq_queues, BFQ plugs I/O dispatching when the queue becomes idle, and keeps the plug until a new request of the queue arrives, or a timeout fires. BFQ does so either to boost throughput or to preserve service guarantees for the queue. More precisely, for such a queue, plugging starts when the queue happens to have either no request enqueued, or no request in flight, that is, no request already dispatched but not yet completed. On the opposite end, BFQ may happen to expire a queue with no request enqueued, without doing any plugging, if the queue still has some request in flight. Unfortunately, such a premature expiration causes the queue to lose its chance to enjoy dispatch plugging a moment later, i.e., when its in-flight requests finally get completed. This breaks service guarantees for the queue. This commit prevents BFQ from expiring an empty queue if the latter still has in-flight requests.

由 Paolo Valente 提交于
To keep I/O throughput high as often as possible, BFQ performs I/O-dispatch plugging (aka device idling) only when beneficial exactly for throughput, or when needed for service guarantees (low latency, fairness). An important case where the latter condition holds is when the scenario is 'asymmetric' in terms of weights: i.e., when some bfq_queue or whole group of queues has a higher weight, and thus has to receive more service, than other queues or groups. Without dispatch plugging, lower-weight queues/groups may unjustly steal bandwidth to higher-weight queues/groups. To detect asymmetric scenarios, BFQ checks some sufficient conditions. One of these conditions is that active groups have different weights. BFQ controls this condition by maintaining a special set of unique weights of active groups (group_weights_tree). To this purpose, in the function bfq_active_insert/bfq_active_extract BFQ adds/removes the weight of a group to/from this set. Unfortunately, the function bfq_active_extract may happen to be invoked also for a group that is still active (to preserve the correct update of the next queue to serve, see comments in function bfq_no_longer_next_in_service() for details). In this case, removing the weight of the group makes the set group_weights_tree inconsistent. Service-guarantee violations follow. This commit addresses this issue by moving group_weights_tree insertions from their previous location (in bfq_active_insert) into the function __bfq_activate_entity, and by moving group_weights_tree extractions from bfq_active_extract to when the entity that represents a group remains throughly idle, i.e., with no request either enqueued or dispatched.
