Subject: [PATCH for-next] RDMA: return -EOPNOSUPP for ODP unsupported device
Date: Sat, 1 Oct 2022 10:00:45 +0800 [thread overview]
Message-ID: <20221001020045.8324-1-lizhijian@fujitsu.com> (raw)
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 unspported by the HCA(such as RXE).
