Subject: [PATCH v3 4/6] RDMA/rxe: Replace ah->pd by ah->ibah.pd
Date: Thu, 22 Jul 2021 16:22:43 -0500	[thread overview]
Message-ID: <20210722212244.412157-5-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210722212244.412157-1-rpearsonhpe@gmail.com>

The pd field in struct rxe_ah is redundant with the pd field in the
rdma-core's ib_ah. Eliminate the pd field in rxe_ah and add an inline
to extract the pd from the ibah field.
