Revision 86e0d6766cf909813474857bd22fdc04c97c0b36 authored by Jens Axboe on 05 March 2021, 15:44:39 UTC, committed by Jens Axboe on 05 March 2021, 15:44:39 UTC
We have this weird true/false return from parking, and then some of the callers decide to look at that. It can lead to unbalanced parks and sqd locking. Have the callers check the thread status once it's parked. We know we have the lock at that point, so it's either valid or it's NULL. Fix race with parking on thread exit. We need to be careful here with ordering of the sdq->lock and the IO_SQ_THREAD_SHOULD_PARK bit. Rename sqd->completion to sqd->parked to reflect that this is the only thing this completion event doesn. Signed-off-by: Jens Axboe <axboe@kernel.dk>
