Subject: [PATCH v3 0/3] nvme: fix hang in path of removing disk
Date: Mon, 22 May 2017 23:05:02 +0800 [thread overview]
Message-ID: <20170522150505.452-1-ming.lei@redhat.com> (raw)
The first two patches fixes hang during removing disk.
The 3rd patch removes blk_mq_abort_requeue_list() since
no one uses it any more.
V3:
- adjust comments about 'Forcibly start all queues'
as suggested by Christoph
V2:
- figure out one big issue is that we should start
queues unconditionally when killing queues
- fix requeue races in another way
Ming Lei (3):
nvme: use blk_mq_start_hw_queues() in nvme_kill_queues()
nvme: avoid to use blk_mq_abort_requeue_list()
blk-mq: remove blk_mq_abort_requeue_list()
