Hello Tejun,
I was trying to do some simple testing ot the CPU controller that is merged into 4.15, and ran immediately into some confusion. In the root cgroup on a freshly booted 4.150-rc1, I try the following:
# pwd /sys/fs/cgroup/unified # echo '+cpu' > cgroup.subtree_control sh: echo: write error: Invalid argument
What am I missing> I presume I'm missing something obvious, although nothing jumped out at me as I read the cgroups-v2.txt file.
Cheers,
Michael
