From 51574e0398a2d93cbf7f26e36b673cd919062268 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 12 Sep 2005 09:52:28 -0700 Subject: [PATCH] [PATCH] IPoIB: fix module removal race Since ipoib uses queue_delayed_work to run flush task on port state events, it must flush scheduled work after unregistering the event handler.
