Merge tag 'cgroup-for-6.17-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup

Pull cgroup fixes from Tejun Heo:
 "This contains two cgroup changes. Both are pretty low risk.

  - Fix deadlock in cgroup destruction when repeatedly
    mounting/unmounting perf_event and net_prio controllers.

    The issue occurs because cgroup_destroy_wq has max_active=1, causing
    root destruction to wait for CSS offline operations that are queued
    behind it.

    The fix splits cgroup_destroy_wq into three separate workqueues to
    eliminate the blocking.

  - Set of->priv to NULL upon file release to make potential bugs to
    manifest as NULL pointer dereferences rather than use-after-free
    errors"
