From 148b4e7ff31e4bb90cf7851ad1bcd305c292be2c Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Mon, 10 Jul 2017 09:22:35 +0300 Subject: [PATCH] nvme-rdma: stop queues instead of simply flipping their state If we move the queues from LIVE state, we might as well stop them (drain for rdma). Do it after we stop the request queues to prevent a stray request sneaking in .queue_rq after we stop the queue.
