Subject: [PATCH 17/17] selftests/cgroup: Test isolation accounting on propagated invalidation
Date: Thu, 20 Aug 2026 20:42:02 +0800 [thread overview]
Message-ID: <20260820124202.517160-18-guopeng.zhang@linux.dev> (raw)
In-Reply-To: <20260820124202.517160-1-guopeng.zhang@linux.dev>
From: Guopeng Zhang <zhangguopeng@kylinos.cn>
State-matrix cases exercise a child invalidated by its parent and a
nested partition invalidated through an already invalid parent.
