This is not consistent because IMHO the clock setup & slack should be
handled equally. So I am asking the sched folks for a policy and I am
leaning towards looking at task-policy in this case instead of prio
because you shouldn't do anything that can delay.

Can't we do that based on is_soft/is_hard flag in hrtimer struct when we apply
the slack in hrtimer_set_expires_range_ns() instead?

We need to decide on a policy first.
You don't want to add overhead on each invocation plus some in-kernel
ask for delta. ->is_soft is not a good criteria.
