Subject: [PATCH 0/6] blk-mq: fix race related with device deletion/reset/switching sched
Date: Tue, 12 Dec 2017 19:02:26 +0800 [thread overview]
Message-ID: <20171212110232.12495-1-ming.lei@redhat.com> (raw)
Hi,
The 1st patch fixes one kernel oops triggered by IOs vs. deleting SCSI
device, and this issue can be triggered in less than 1min on scsi_debug.
The other 5 patch fixes recent Yi Zhang's reports about his NVMe stress
tests, most of them are related with switching io sched, NVMe reset or
updating nr_hw_queues.
Thanks,
Ming
Ming Lei (6):
blk-mq: quiesce queue before freeing queue
blk-mq: support concurrent blk_mq_quiesce_queue()
blk-mq: quiesce queue during switching io sched and updating
nr_requests
blk-mq: avoid to map CPU into stale hw queue
blk-mq: fix race between updating nr_hw_queues and switching io sched
nvme: remove .init_request callback
