I don't think this does what's advertised if you mean it to keep a count as the atomics seem to imply. (->open is only called on first open and ->release on last close. openers was a historical 2.4 field that used to count opens but now just flags whether sd is open or not. Secondly, if you really want an openers count (which I remember SCSI rendering a bad idea ages ago), that's held in struct block_device as openers, isn't it? So there's no need to duplicate this in SCSI.
