Message-Id: <1219019197-17744-1-git-send-email-dbaryshkov@gmail.com> Date: Mon, 18 Aug 2008 04:26:37 +0400 From: Dmitry Baryshkov <dbaryshkov@...il.com> To: linux-kernel@...r.kernel.org Cc: peterz@...radead.org, mingo@...hat.com, Dmitry Baryshkov <dbaryshkov@...il.com> Subject: [PATCH] lockdep: fix spurious 'inconsistent lock state' warning Since f82b217e3513fe3af342c0f3ee1494e86250c21c lockdep can output spurious warnings related to hwirqs due to hardirq_off shrinkage from int to bit-sized flag. Guard it with double negation to fix the warning.
