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