From 875e08294911b3cb8c60416d64d990809421de29 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Thu, 8 Oct 2015 21:28:56 +0800 Subject: [PATCH] net/nfnetlink: lockdep_nfnl_is_held can be boolean This patch makes lockdep_nfnl_is_held return bool to improve readability due to this particular function only using either one or zero as its return value.
