Subject: [PATCH for-rc v3 6/6] RDMA/rxe: Only allow invalidate for appropriate MRs
Date: Thu,  9 Sep 2021 15:44:57 -0500	[thread overview]
Message-ID: <20210909204456.7476-7-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210909204456.7476-1-rpearsonhpe@gmail.com>

Local and remote invalidate operations are not allowed by IBA for
MRs created by (re)register memory verbs. This patch checks the
MR type in rxe_invalidate_mr().
