516 *
517 * Principe is simple, we keep a list of sub allocation in offset
518 * order (first entry has offset == 0, last entry has the highest
519 * offset).
520 *
521 * When allocating new object we first check if there is room at
522 * the end total_size - (last_object_offset + last_object_size) >=
523 * alloc_size. If so we allocate new object there.
524 *
525 * When there is not enough room at the end, we start waiting for
526 * each sub object until we reach object_offset+object_size >=
527 * alloc_size, this object then become the sub object we return.
528 *
529 * Alignment can't be bigger than page size.
530 *
531 * Hole are not considered for allocation to keep things simple.
532 * Assumption is that there won't be hole (all object on same
533 * alignment).
