Subject: [PATCH for-next v3 03/12] RDMA/rxe: Remove redundant scheduling of rxe_completer
Date: Fri, 29 Mar 2024 09:55:06 -0500 [thread overview]
Message-ID: <20240329145513.35381-6-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20240329145513.35381-2-rpearsonhpe@gmail.com>
In rxe_post_send_kernel() if the qp is in the error state after
posting the work requests the rxe_completer() task is scheduled.
But, the only way to move the qp into the error state is to call
rxe_qp_error() which also schedules the rxe_completer() task to drain
the queues. Calling it a second time has no effect. This commit
removes the redundant call.
