From f0163ac45b40bd032b877c747796146d52d4e800 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Tue, 13 Nov 2007 21:00:09 -0800 Subject: [PATCH] [E1000]: Fix schedule while atomic when called from mii-tool. mii-tool can cause the driver to call msleep during nway reset, bugzilla.kernel.org bug 8430. Fix by simply calling reinit_locked outside of the spinlock, which is safe from ethtool, so it should be safe from here.
