Hi,
I'm stil working on rdd && new pressure stats.
pressure stats in cgroup are only available in cgroupv2.
so it's working for qemu, but I don't have counter for lxc as it's
still using cgroupv1.
I see that wolfgang have already add support for cgroupv2 in LXC::Cgroups,
I would like to enable it to test if I can get correct pressure info.
does somebody known how to enable it ? some sysctl or grub option maybe ?

adding systemd.unified_cgroup_hierarchy=1 to the kernel commandline
(/etc/default/grub or /etc/kernel/cmdline (ZFS on UEFI) ) should work:
