Roland Dreier a77a57a1a2 IPoIB: Fix deadlock on RTNL in ipoib_stop() ... Commit c8c2afe3 ("IPoIB: Use rtnl lock/unlock when changing device flags") added a call to rtnl_lock() in ipoib_mcast_join_task(), which is run from the ipoib_workqueue. However, ipoib_stop() (which is run inside rtnl_lock()) flushes this workqueue, which leads to a deadlock if the join task is pending. Fix this by simply not flushing the workqueue from ipoib_stop(). It turns out that we really don't care about workqueue tasks running during or after ipoib_stop(), as long as we make sure to flush the workqueue before unregistering a netdev. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1114>. Signed-off-by: Roland Dreier <rolandd@cisco.com>		2008-08-19 15:01:32 -07:00
