429/* sub-allocation manager, it has to be protected by another lock.
430 * By conception this is an helper for other part of the driver
431 * like the indirect buffer or semaphore, which both have their
432 * locking.
433 *
434 * Principe is simple, we keep a list of sub allocation in offset
435 * order (first entry has offset == 0, last entry has the highest
436 * offset).
437 *
438 * When allocating new object we first check if there is room at
439 * the end total_size - (last_object_offset + last_object_size) >=
440 * alloc_size. If so we allocate new object there.
441 *
442 * When there is not enough room at the end, we start waiting for
443 * each sub object until we reach object_offset+object_size >=
444 * alloc_size, this object then become the sub object we return.
445 *
446 * Alignment can't be bigger than page size.
447 *
448 * Hole are not considered for allocation to keep things simple.
449 * Assumption is that there won't be hole (all object on same
450 * alignment).
