502 * like the indirect buffer or semaphore, which both have their
503 * locking.
504 *
505 * Principe is simple, we keep a list of sub allocation in offset
506 * order (first entry has offset == 0, last entry has the highest
507 * offset).
508 *
509 * When allocating new object we first check if there is room at
510 * the end total_size - (last_object_offset + last_object_size) >=
511 * alloc_size. If so we allocate new object there.
512 *
513 * When there is not enough room at the end, we start waiting for
514 * each sub object until we reach object_offset+object_size >=
515 * alloc_size, this object then become the sub object we return.
516 *
517 * Alignment can't be bigger than page size.
518 *
519 * Hole are not considered for allocation to keep things simple.
520 * Assumption is that there won't be hole (all object on same
521 * alignment).
