From 43d781b9fa562f0c6e50f62c870fbfeb9dc85213 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Mon, 7 Sep 2020 15:09:18 +0300 Subject: RDMA: Allow fail of destroy CQ Like any other verbs objects, CQ shouldn't fail during destroy, but mlx5_ib didn't follow this contract with mixed IB verbs objects with DEVX. Such mix causes to the situation where FW and kernel are fully interdependent on the reference counting of each side. Kernel verbs and drivers that don't have DEVX flows shouldn't fail.
