Subject: [PATCH rdma-next v3 06/11] RDMA: Add dedicated QP resource tracker function
Date: Tue, 23 Jun 2020 14:30:38 +0300 [thread overview]
Message-ID: <20200623113043.1228482-7-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 QP,
add a dedicated callback function.
