From mboxrd@z Thu Jan 1 00:00:00 1970 From: nitzanc@mellanox.com (Nitzan Carmi) Date: Tue, 20 Mar 2018 11:07:29 +0000 Subject: [PATCH 1/2] nvme-rdma: Allow DELETING state change failure in error_recovery Message-ID: <20180320110730.24070-1-nitzanc@mellanox.com> While error recovery is ongoing, it is OK to move ctrl to DELETING state (from concurrent delete_work). Thus we don't need a warning for that case.
