Subject: [PATCH mlx5-next v2 16/20] IB/mlx5: Add DEVX support for modify and query commands
Date: Sun, 17 Jun 2018 13:00:02 +0300 [thread overview]
Message-ID: <20180617100006.30663-17-leon@kernel.org> (raw)
In-Reply-To: <20180617100006.30663-1-leon@kernel.org>
From: Yishai Hadas <yishaih@mellanox.com>
Add support in DEVX for modify and query commands, the required lock is
taken (i.e. READ/WRITE) by the KABI infrastructure accordingly.
