Subject: [PATCH -next] cgroup_freezer: update comment for freezer_css_online()
Date: Wed, 17 Apr 2024 03:50:28 +0000

From: Xiu Jianfeng <xiujianfeng@huawei.com>

The freezer->lock was replaced by freezer_mutex in commit e5ced8ebb10c
("cgroup_freezer: replace freezer->lock with freezer_mutex"), so the
comment here is out-of-date, update it.
