From a9851832857dc1e4efefca1713f5cff3e168a25c Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 29 Apr 2011 10:42:19 +0200 Subject: [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.
