percpu: introduce helper to determine if two regions overlap While block hints were always accurate, it's possible when spanning across blocks that we miss updating the chunk's contig_hint. Rather than rely on correctness of the boundaries of hints, do a full overlap comparison. A future patch introduces the scan_hint which makes the contig_hint slightly fuzzy as they can at times be smaller than the actual hint. Signed-off-by: Dennis Zhou <dennis@kernel.org>
