Subject: [GIT PULL] cgroup fixes for v5.7-rc7

Hello, Linus.

* Reverted stricter synchronization for cgroup recursive stats which was
  prepping it for event counter usage which never got merged. The change was
  causing performation regressions in some cases.

* Restore bpf-based device-cgroup operation even when cgroup1 device cgroup
  is disabled.

* An out-param init fix.

Thanks.
