Subject: [PATCH for-next v2 09/18] RDMA/rxe: Simplify reset state handling in rxe_resp.c
Date: Fri, 21 Oct 2022 15:01:10 -0500	[thread overview]
Message-ID: <20221021200118.2163-10-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20221021200118.2163-1-rpearsonhpe@gmail.com>

Make rxe_responder() more like rxe_completer() and take qp reset
handling out of the state machine.
