From 778af2b4f14a7702886b05248c0cedac9c2b5587 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 3 Jul 2009 08:30:00 -0500 Subject: [084/254] drivers/net: vortex fix locking issues Argh, cut and paste wasn't enough... Use this patch instead. It needs an irq disable. But, believe it or not, on SMP this is actually better. If the irq is shared (as it is in Mark's case), we don't stop the irq of other devices from being handled on another CPU (unfortunately for Mark, he pinned all interrupts to one CPU).
