Subject: [net-next 01/14] i40e: Replace spin_is_locked() with lockdep
Date: Wed, 14 Nov 2018 15:10:19 -0800	[thread overview]
Message-ID: <20181114231032.4013-2-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20181114231032.4013-1-jeffrey.t.kirsher@intel.com>

From: Lance Roy <ldr709@gmail.com>

lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().
