This patch makes lockdep_rtnl_is_held return bool due to this particular function only using either one or zero as its return value. In another patch lockdep_is_held is also made return bool. No functional change. Signed-off-by: Yaowei Bai <bywxiaobai@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
