Subject: [PATCH net-next 1/7] sched: un-hide lockdep_tasklist_lock_is_held() for !LOCKDEP
Date: Wed, 16 Sep 2020 11:45:22 -0700	[thread overview]
Message-ID: <20200916184528.498184-2-kuba@kernel.org> (raw)
In-Reply-To: <20200916184528.498184-1-kuba@kernel.org>

We're trying to make LOCKDEP-related function declarations
visible to the compiler and depend on dead code elimination
to remove them.

Make lockdep_tasklist_lock_is_held() visible.
