[PATCH 05/12] xfs: clean up log ticket overrun debug output

Dave Chinner
2010-05-07T05:39:05Z

Push the error message output when a ticket overrun is detected
into the ticket printing functions. Also remove the debug version
of the code as the production version will still panic just as
effectively on a debug kernel via the panic mask being set.
