Subject: [PATCH for-next v2 1/2] RDMA/rxe: Let rdma-core manage PDs
Date: Thu, 29 Jul 2021 17:30:10 -0500	[thread overview]
Message-ID: <20210729223010.31007-2-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210729223010.31007-1-rpearsonhpe@gmail.com>

Currently several rxe objects hold references to PDs which are ref-
counted. This replicates work already done by RDMA core which takes
references to PDs in the ib objects which are contained in the rxe
objects. This patch removes struct rxe_pd from rxe objects and removes
reference counting for PDs except for PD alloc and PD dealloc. It also
adds inline extractor routines which return PDs from the PDs in the
ib objects. The names of these are made consistent including a rxe_
prefix.
