Merge branch 'for-5.7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
- 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.
* 'for-5.7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
device_cgroup: Cleanup cgroup eBPF device filter code
xattr: fix uninitialized out-param
Revert "cgroup: Add memory barriers to plug cgroup_rstat_updated() race window"
