From fe8998c5e3b173f3d5c450bbde6173e7fbe5158d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 12 Dec 2010 16:45:14 +0100 Subject: sungem: update gp->reset_task flushing gp->reset_task_pending is always set right before reset_task is scheduled and as there is no synchronization between the setting and scheduling, busy looping on reset_task_pending before flushing reset_task doesn't really buy anything. Directly flush gp->reset_task on suspend and cancel on detach. Signed-off-by: Tejun Heo Cc: "David S.
