From mboxrd@z Thu Jan 1 00:00:00 1970 From: Subject: [PATCH v1] net: driver: stmicro: Remove some useless the lock protection Date: Fri, 23 May 2014 19:05:03 +0800 Message-ID: <1400843103-19433-1-git-send-email-Wei.Yang@windriver.com> Mime-Version: 1.0 Content-Type: text/plain Cc: , To: Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org From: Yang Wei kernel always invokes a pair of rtnl_lock adn rtnl_unlock to protect dev_ethtool(), so its not neccessary to invoke spin_lock/unlock in ethtool_ops.
