Hi All,

While understanding the DRBD code,  we observed that count (open_cnt) is
locked during incrementing in the DRBD_OPEN function. But it was not locked
during decrementing open_cnt count.  Can it create race condition and due to
that open_cnt doesn't get decrmented and raise the issue "Device is held
open by someone".

Please share your thoughts.
