From: Michael Mueller Date: Tue, 3 Mar 2020 15:42:01 +0000 (+0100) Subject: s390/diag: fix display of diagnose call statistics X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6c7c851f1b666a8a455678a0b480b9162de86052;p=linux.git s390/diag: fix display of diagnose call statistics Show the full diag statistic table and not just parts of it. The issue surfaced in a KVM guest with a number of vcpus defined smaller than NR_DIAG_STAT.
