Subject: [PATCH for-next v5 2/6] RDMA/rxe: Change AH objects to indexed
Date: Tue, 5 Oct 2021 20:58:11 -0500 [thread overview]
Message-ID: <20211006015815.28350-3-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20211006015815.28350-1-rpearsonhpe@gmail.com>
Make changes to rxe_param.h and rxe_pool.c to allow indexing of AH
objects. Valid indices are non-zero so older providers can be detected.
Signed-off-by: Bob Pearson <rpearsonhpe@gmail.com>
