From 60be6b9a41cb0da0df7a9f11486da56baebf04cd Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 3 Jul 2006 00:25:26 -0700 Subject: [PATCH] lockdep: annotate on-stack completions lockdep needs to have the waitqueue lock initialized for on-stack waitqueues implicitly initialized by DECLARE_COMPLETION(). Annotate on-stack completions accordingly. Has no effect on non-lockdep kernels.
