Subject: [PATCH rdma-next v1 07/11] RDMA: Add dedicated CM_ID resource tracker function
Date: Wed, 27 May 2020 16:54:04 +0300 [thread overview]
Message-ID: <20200527135408.480878-8-leon@kernel.org> (raw)
In-Reply-To: <20200527135408.480878-1-leon@kernel.org>
From: Maor Gottlieb <maorg@mellanox.com>
In order to avoid double multiplexing of the resource when it's
cm id, add a dedicated callback function.
In addition remove fill_res_entry which is not used anymore.
