Subject: [PATCH 2/2] nvme-rdma: move admin queue cleanup to nvme_rdma_free_ctrl
Date: Thu, 14 Jul 2016 12:17:30 +0300 [thread overview]
Message-ID: <578758AA.5050908@grimberg.me> (raw)
In-Reply-To: <57875835.5050001@grimberg.me>
> This patch introduces asymmetry between create and destroy

> 1. destroy queue
> 2. delete controller

> Or more specifically:
> 1. own the controller deletion (make sure we are not

> 2. get rid of inflight reconnects (which also destroy and

> 3. destroy the queue
> 4. safely queue controller deletion
