[PATCH] IPoIB: Fix device removal race
Currently we may have work scheduled in default kernel workqueue when the device is going down. The device could get freed before this workqueue gets serviced. I am actually seeing this causing system hangs. The following patch fixes this by using ipoib_workqueue which gets flushed when the device is going down. Signed-off-by: Michael S.
