But even then, the line https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/kernel/cgroup/cgroup-v1.c?h=v5.11-rc3#n1012 would select only 'enabled' controllers, wouldn't it?
It's possible I missed something but if this means that cgroup_no_v1= doesn't hold to its expectations, I'd suggest adding proper Fixes: tag to the patch. Thanks, Michal
