From e82080e1f456467cc185fe65ee69fe9f9bd0b576 Mon Sep 17 00:00:00 2001 From: Janosch Frank Date: Wed, 13 Jan 2021 11:56:26 -0500 Subject: s390: uv: Fix sysfs max number of VCPUs reporting The number reported by the query is N-1 and I think people reading the sysfs file would expect N instead. For users creating VMs there's no actual difference because KVM's limit is currently below the UV's limit.
