From 90140624e8face94207003ac9a9d2a329b309d68 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Mon, 9 Jul 2018 12:49:05 +0300 Subject: nvme-rdma: unquiesce queues when deleting the controller If the controller is going away, we need to unquiesce the IO queues so that all pending request can fail gracefully before moving forward with controller deletion. Do that before we destroy the IO queues so blk_cleanup_queue won't block in freeze.
