mainline inclusion from mainline-v5.12-rc1 commit da70862efe0065bada33d67a903270cdbbaf07d9 issue: #I4RVJ4 CVE: CVE-2021-4197

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

Signed-off-by: Yu Changchun --------------------------------

The functions cgroup_threads_write and cgroup_procs_write are almost identical. In order to reduce duplication, factor out the common code in similar fashion we already do for other threadgroup/task functions. No functional changes are intended.
