Hi Steve,
That attached patch stops the kernel from oopsing, but it still tries
endlessly to send with softRoCE. I'm having better luck with softIWarp - with
some other patches, I can run generic/001 to completion with that transport.

cifs: Fix oops due to uncleared server->smbd_conn in reconnect
In smbd_destroy(), clear the server->smbd_conn pointer after freeing the
smbd_connection struct that it points to so that reconnection doesn't get
confused.
