From 6e07ebd84eef00be9e169a6d15a0bc20b06578fa Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 12 Dec 2010 16:45:14 +0100 Subject: [PATCH] drivers/net: remove unnecessary flush_scheduled_work() calls janz-ican3, sh_eth, skge and vxge don't use workqueue at all and there is no reason to flush the system_wq. Drop flush_scheduled_work() calls and references to workqueue. Signed-off-by: Tejun Heo Cc: "David S.
