Subject: [PATCH rfc 07/10] nvme-rdma: Don't rearm the CQ when polling directly
Date: Thu, 9 Mar 2017 15:16:39 +0200 [thread overview]
Message-ID: <1489065402-14757-8-git-send-email-sagi@grimberg.me> (raw)
In-Reply-To: <1489065402-14757-1-git-send-email-sagi@grimberg.me>
We don't need it as the core polling context will take
are of rearming the completion queue.
