Subject: [net-next 13/17] net/mlx5: Remove unnecessary spin lock protection
Date: Wed, 26 May 2021 21:36:05 -0700 [thread overview]
Message-ID: <20210527043609.654854-14-saeed@kernel.org> (raw)
In-Reply-To: <20210527043609.654854-1-saeed@kernel.org>
From: Eli Cohen <elic@nvidia.com>
Taking lag_lock to access ldev->tracker is meaningless in the context of
do_bond() and mlx5_lag_netdev_event().
