525 * locking.
526 *
527 * Principe is simple, we keep a list of sub allocation in offset
528 * order (first entry has offset == 0, last entry has the highest
529 * offset).
530 *
531 * When allocating new object we first check if there is room at
532 * the end total_size - (last_object_offset + last_object_size) >=
533 * alloc_size. If so we allocate new object there.
534 *
535 * When there is not enough room at the end, we start waiting for
536 * each sub object until we reach object_offset+object_size >=
537 * alloc_size, this object then become the sub object we return.
538 *
539 * Alignment can't be bigger than page size.
540 *
541 * Hole are not considered for allocation to keep things simple.
542 * Assumption is that there won't be hole (all object on same
543 * alignment).
