Subject: [PATCHSET 0/3] Split queue lock into submission/completion locks
Date: Thu, 17 May 2018 09:02:14 -0600	[thread overview]
Message-ID: <1526569337-3489-1-git-send-email-axboe@kernel.dk> (raw)

This series is on top of the previous work from yesterday, including
Christophs patch. It splits nvmeq->q_lock into two locks:

1) ->sq_lock, that protects the submission side of things
2) ->cq_lock, that protects the completion side

This also means that we can drop the IRQ safe nature of the submission
side locking.
