Revision a9851832857dc1e4efefca1713f5cff3e168a25c authored by Heiko Carstens on 29 April 2011, 08:42:19 UTC, committed by Martin Schwidefsky on 29 April 2011, 08:42:25 UTC 
[S390] irqstats: fix counting of pfault, dasd diag and virtio irqs
 
pfault, dasd diag and virtio all use the same external interrupt number.
The respective interrupt handlers decide by the subcode if they are
meant to handle the interrupt.
Counting is currently done before looking at the subcode which means
each handler counts an interrupt even if it is not handling it.
Fix this by moving the kstat code after the code which looks at the
subcode.
