- make qdio_trace a per device view - remove s390dbf exceptions - remove CONFIG_QDIO_DEBUG, not needed anymore if we check for the level before calling sprintf - use snprintf for dbf entries - add start markers to see if the dbf view wrapped - add a global error view for all queues Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
