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 <redacted> --- include/linux/rtnetlink.h | 6 +++--- net/core/rtnetlink.c | 2 +- 2 files changed, 4 insertions(+), 4 deletions(-)
