[PATCH 23/25] netfilter: Use bool function return values of true/false not 1/0

From: Joe Perches <joe@perches.com>
Date: 2015-03-30 23:49:07
Also in: lkml, netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

Use the normal return values for bool functions
