When nfs_put_client is called it calls nfs_callback_down. It calls nfs_callback_down_net() which should call svc_shutdown_net which closes all sockets. It then calls svc_exit_thread() which finds some sockets still open (hence the bug). There are no permanent sockets (TCP listeners and UDP), only temporary sockets (TCP connections), so it certainly seems that svc_shutdown_net has run. The commit mentioned fixed a race were svc_shutdown_net might miss some sockets. So I think this trace does match that commit. If you can get a BUG trace with a newer kernel that has that commit I'd certainly like to see it. For now: closing as suggested in comment #2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
