Subject: [PATCH rdma-next v3 05/11] RDMA: Add a dedicated CQ resource tracker function
Date: Tue, 23 Jun 2020 14:30:37 +0300	[thread overview]
Message-ID: <20200623113043.1228482-6-leon@kernel.org> (raw)
In-Reply-To: <20200623113043.1228482-1-leon@kernel.org>

From: Maor Gottlieb <maorg@mellanox.com>

In order to avoid double multiplexing of the resource when it's CQ,
add a dedicated callback function.
