For single-partition devices it is just bd_openers but I am more intersted in multi-partition case. Here I need to know about sum of opens for all partitions including the whole device. It appears that for a container bd_openers is incremented for every open of itself and for the _first_ open of partition and bd_part_count is incremented for every (including first) open of partition. So bdev->bd_contains->bd_openers + bdev->bd_contains->bd_part_count really gives an access (number of opened partitions but this is unknown otherwise).
Thank you
