This changelog doesn't make sense.
There can be only one active sched_clock, but that does no mean, that
you cannot have different implementations compiled in.
So if you disable this config which sched_clock is your kernel using?
And if you enable it, how is guaranteed that you end up with the ttc
sched_clock as the active one? Just due to initcall ordering?
Thanks,
