From ba697f40dbb704956a4cf67a7845b538015a01ea Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 4 May 2010 04:47:25 +0200 Subject: lockdep: Provide off case for redundant_hardirqs_on increment We forgot to provide a !CONFIG_DEBUG_LOCKDEP case for the redundant_hardirqs_on stat handling. Manage that in the headers with a new __debug_atomic_inc() helper. Fixes: kernel/lockdep.c:2306: error: 'lockdep_stats' undeclared (first use in this function) kernel/lockdep.c:2306: error: (Each undeclared identifier is reported only once kernel/lockdep.c:2306: error: for each function it appears in.)
