Yes, the for looks better, but perhaps like that:

	unsigned int bucket_id = UCLAMP_BUCKETS;

 	/*
 	 * Both min and max clamps are MAX aggregated, thus the topmost
 	 * bucket with some tasks defines the rq's clamp value.
 	 */
	for (; bucket_id >= 0; --bucket_id) {

GCC will be clever and figure that unsigned will never be smaller than 0
and turn the above into an infinite loop or something daft.

That is; use 'int', not 'unsigned int' for bucket_id.

Right, which remembers me now why I originally went for a do { } while();
