From 8688cfcebf09b84385b5e2c461ae08fcde8a5d18 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 3 Jul 2006 00:25:39 -0700 Subject: [PATCH] [PATCH] lockdep: annotate forcedeth.c disable_irq() nv_do_nic_poll() is called from timer softirqs, which has interrupts enabled, but np->lock might also be taken by some other interrupt context. The driver does disable_irq() to get around this problem, so annotate the disable_irq()/enable_irq() calls for lockdep. Has no effect on non-lockdep kernels.
