Subject: [PATCH cgroup/for-next 0/3] Improve clarity of cgroup destruction process

From: Chen Ridong <chenridong@...wei.com>

This series aims to improve the clarity of the cgroup destruction
mechanism. Since the destruction process has been split across three
workqueues, this patch set introduces helper functions and renames
existing ones to enhance readability. As a result, the logic now follows
a more straightforward one-to-one correspondence, making the overall flow
easier to understand. Besides, patch 1 removes the redundancy online_cnt.

This series is based on 04a4d6c24eef8a1fc89d8b6129ac00ca2f638aff for the
cgroup/for-next branch.

Chen Ridong (3):
  cgroup: remove redundancy online_cnt
  cgroup: add css_free helper
  cgroup: rename css offline related functions
