From 0a9da4bd8eb30fb3f36e841c2cc72e426a17bbe2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 3 Jul 2006 00:25:24 -0700 Subject: [PATCH] [PATCH] lockdep: annotate 3c59x.c disable_irq() 3c59x.c's vortex_timer() function knows that vp->lock can only be used by an irq context that it disabled - and can hence take the vp->lock without disabling hardirqs. Teach lockdep about this. Has no effect on non-lockdep kernels.
