From 53c2d5b14a82f6e7f0f8089083972df20e66a354 Mon Sep 17 00:00:00 2001 From: Li Zhijian Date: Sat, 1 Oct 2022 10:00:45 +0800 Subject: [PATCH] RDMA/core: return -EOPNOSUPP for ODP unsupported device ib_reg_mr(3) which is used to register a MR with specific access flags for specific HCA will set errno when something go wrong. So, here we should return the specific -EOPNOTSUPP when the being requested ODP access flag is unsupported by the HCA(such as RXE).
