Most likely (you'd not be able either: turn on RT policy, migrate the
process or enable CPU controller, i.e. a step that'd lead to an invalid
state).

I'm curious, what would be your use case for turning RT group
schedulling on?

I don't necessarily have any usecase, I just forgot that option was even configurable. Even though i knew about it's existence previously.

Arch disables it by default and this seems to be a good choice. but cgroupsv2 docs don't say that this behavior is conditioned on that option so I forgot it existed.


Thanks,
Michal
