Subject: [PATCH rdma-next v3 04/11] RDMA: Add dedicated MR resource tracker function
Date: Tue, 23 Jun 2020 14:30:36 +0300	[thread overview]
Message-ID: <20200623113043.1228482-5-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 MR,
add a dedicated callback function.
