What is your rationale for this?
I think there is value in allowing the kernel to support a version while
disabling it by default. This allows it to be used for experimentation,
without much risk of it being used in production until it is deemed to
be really ready.
I like the rest of the patch set, and withdraw my comments about the
earlier patch set which were due to a hasty misunderstanding.
Thanks,
