From 6951b12a0fe7fc64789f2c4d62d2a304e93836a8 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 18 Aug 2008 04:26:37 +0400 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.
