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

From: Tejun Heo
Date: Wed May 27 2020 - 10:21:24 EST


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.
