From e745165c6d235c03e9fa0e57984ca6fd3d3b2c50 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 3 Jul 2006 00:25:23 -0700 Subject: [PATCH] lockdep: annotate 8390.c disable_irq() 8390.c knows that ei_local->page_lock can only be used by an irq context that it disabled - and can hence take the ->page_lock without disabling hardirqs. Teach lockdep about this. Has no effect on non-lockdep kernels.
