Merge tag 'cgroup-for-6.12-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup

Pull cgroup fixes from Tejun Heo:

 - cgroup_bpf_release_fn() could saturate system_wq with
   cgrp->bpf.release_work which can then form a circular dependency
   leading to deadlocks. Fix by using a dedicated workqueue. The
   system_wq's max concurrency limit is being increased separately.

 - Fix theoretical off-by-one bug when enforcing max cgroup hierarchy
   depth
