Subject: [PATCH -next] cgroup: avoid invalid loop in cgroup_no_v1()
Date: Fri, 19 Apr 2024 08:53:16 +0000 [thread overview]
Message-ID: <20240419085316.957277-1-xiujianfeng@huawei.com> (raw)
We should break the for_each_subsys loop after the token matches
the name of subsys and cgroup_no_v1_mask is set.
