From b25ba45fcfdbd79317d62174b240dca2731e9927 Mon Sep 17 00:00:00 2001 From: Muhammad Adeel Date: Fri, 7 Feb 2025 14:24:32 +0000 Subject: [PATCH] cgroup: Remove steal time from usage_usec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit db5fd3cf8bf41b84b577b8ad5234ea95f327c9be ] The CPU usage time is the time when user, system or both are using the CPU. Steal time is the time when CPU is waiting to be run by the Hypervisor. It should not be added to the CPU usage time, hence removing it from the usage_usec entry.
