Date: Sun, 19 Feb 2012 18:29:11 +0400 From: Konstantin Khlebnikov <khlebnikov@...nvz.org> To: Tejun Heo <tj@...nel.org>, Christoph Lameter <cl@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org Subject: [PATCH] percpu: fix generic definition of __this_cpu_add_and_return() This patch adds missed "__" into function prefix. Otherwise on all archectures (except x86) it expands to irq/preemtion-safe variant: _this_cpu_generic_add_return(), which do extra irq-save/irq-restore. Optimal generic implementation is __this_cpu_generic_add_return().
