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.Isn't there a place where a default definition of this can be defined? Instead of adding it separately to every architecture.
Not that I would know about such a place - and all other atomic* macro definitions also suggest that there is no such place. Kind regards, Sven
