Introduce an *_dec_not_zero operation. Make this a special case of *_add_unless because batman-adv uses atomic_dec_not_zero in different places like re-broadcast queue or aggregation queue management. There are other non-final patches which may also want to use this macro. Reported-by: David S. Miller <davem@davemloft.net> Signed-off-by: Sven Eckelmann <sven@narfation.org>
