Subject: [PATCH v4 10/10] IB/mlx5: Simplify completion into a wait_event
Date: Thu, 27 Oct 2016 12:29:14 +0530 [thread overview]
Message-ID: <1477551554-30349-11-git-send-email-binoy.jayan@linaro.org> (raw)
In-Reply-To: <1477551554-30349-1-git-send-email-binoy.jayan@linaro.org>
Convert the completion 'mlx5_ib_umr_context:done' to a wait_event as it
just waits for the return value to be filled.
