See the man page:

    Due to the lack of consensus in the kernel community, the CPU controller
    support on the unified cgroup hierarchy requires out-of-tree kernel patches.
    See cgroup-v2-cpu.txt[3].

I think that's pretty clear. If you think it should be made more clear, let
me know how.

Also, I'll repeat what I wrote on the PR: that patch has no effect on v1 users,
or on v2-vanilla-kernel users, and only affects v2-patched-kernel users.
And what Tejun Heo said: the opposition upstream is not to the details of
the interface, but to general cgroups-v2 design. It's a bit late for that, but
even if the design is significantly changed, the interface is likely to be as
proposed in those patches.
