From 2084b114e3fb0d84e5882f5ee6c7039be52da715 Mon Sep 17 00:00:00 2001 From: Flavio Leitner Date: Tue, 5 Apr 2011 04:27:43 +0000 Subject: e1000e: fix stats locking in e1000_watchdog_task Just move the unlock down a bit because it unlocks too early leaving a chance for get_stats64() run in parallel while it is still accessing the stats.
