From 9731698ecb9c851f353ce2496292ff9fcea39dff Mon Sep 17 00:00:00 2001 From: Andrey Ryabinin Date: Mon, 15 Nov 2021 19:46:04 +0300 Subject: cputime, cpuacct: Include guest time in user time in cpuacct.stat cpuacct.stat in no-root cgroups shows user time without guest time included int it. This doesn't match with user time shown in root cpuacct.stat and /proc//stat. This also affects cgroup2's cpu.stat in the same way. Make account_guest_time() to add user time to cgroup's cpustat to fix this.
