Improve s390 debug feature usage: - log busy bit in dbf - increase size of dbf views - consistent logging of qdio api calls to setup view - print subchannel number so one can associate the interface with the dbf data - only log events to one view Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
