From: Sven Eckelmann <sven@xxxxxxxxxxxxx> 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. > > Reported-by: David S.
