From 7cc8944e13c73374b6f33b39ca24c0891c87b077 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Fri, 9 Oct 2015 11:07:06 +0200 Subject: s390/pci: reshuffle struct used to write debug data zpci_err_insn writes stale stack content to the debugfs. Ensure that the struct in zpci_err_insn is ordered in a way that we don't have uninitialized holes in it. In addition to that add the packed attribute.
