This is a collection of patches that greatly improve CFQ performance in some circumstances. - Change the idling logic to only kick in after a request is done and we are deciding what to do. Before the idling included the request service time, so it was hard to adjust. Now it's true think/idle time. - Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep it in control for sync and sequential (or close to) workloads. - Expire queues immediately and move on to other busy queues, if we are not going to idle after the current one finishes. - Don't rearm idle timer if there are no busy queues. Just leave the system idle. Signed-off-by: Jens Axboe <axboe@suse.de>

Patch originally from Vasily Tarasov <vtaras@sw.ru> If you set io-priority of process 1 using sys_ioprio_set system call by another process 2 (like ionice do), then cfq_init_prio_data() function sets priority of process 2 (current) on queue of process 1 and clears the flag, that designates change of ioprio. So the process 1 will work like with priority of process 2. I propose not to call cfq_init_prio_data() on io-priority change, but only mark queue as queue with changed prority. Every time when new request comes cfq-scheduler checks for this flag and atomaticaly changes priority of queue to new value. Signed-off-by: Jens Axboe <axboe@suse.de>

Jens Axboe authored
A process flag to indicate whether we are doing sync io is incredibly ugly. It also causes performance problems when one does a lot of async io and then proceeds to sync it. Part of the io will go out as async, and the other part as sync. This causes a disconnect between the previously submitted io and the synced io. For io schedulers such as CFQ, this will cause us lost merges and suboptimal behaviour in scheduling. Remove PF_SYNCWRITE completely from the fsync/msync paths, and let the O_DIRECT path just directly indicate that the writes are sync by using WRITE_SYNC instead.

We cannot update them if the user changes nr_requests, so don't set it in the first place. The gains are pretty questionable as well. The batching loss has been shown to decrease throughput. Signed-off-by: Jens Axboe <axboe@suse.de>

We already drop the refcount in elevator_exit(), and as we're setting 'e' to NULL, we'll never take that branch anyway. Finally, as 'e' is a local var that isn't referenced afterwards, setting it to NULL is pointless. Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Jens Axboe <axboe@suse.de>

Paolo 'Blaisorblade' Giarrusso authored
The queue lock can be taken from interrupts so it must always be taken with irq disabling primitives. Some primitives already verify this. blk_start_queue() is called under this lock, so interrupts must be disabled. Also document this requirement clearly in blk_init_queue(), where the queue spinlock is set.
