Bisected to the following commit: 358f70da49d77c43f2ca11b5da584213b2add29c is the first bad commit commit 358f70da49d77c43f2ca11b5da584213b2add29c Author: Tejun Heo <tj@xxxxxxxxxx> Date: Tue Jan 9 08:29:50 2018 -0800 blk-mq: make blk_abort_request() trigger timeout path With issue/complete and timeout paths now using the generation number and state based synchronization, blk_abort_request() is the only one which depends on REQ_ATOM_COMPLETE for arbitrating completion. There's no reason for blk_abort_request() to be a completely separate path. This patch makes blk_abort_request() piggyback on the timeout path instead of trying to terminate the request directly. This removes the last dependency on REQ_ATOM_COMPLETE in blk-mq. Note that this makes blk_abort_request() asynchronous - it initiates abortion but the actual termination will happen after a short while, even when the caller owns the request. AFAICS, SCSI and ATA should be fine with that and I think mtip32xx and dasd should be safe but not completely sure. It'd be great if people who know the drivers take a look. v2: - Add comment explaining the lack of synchronization around ->deadline update as requested by Bart.
