Subject: [PATCHv3] atomic: add *_dec_not_zero
Date: Sun, 29 May 2011 09:13:20 +0200
> 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.
