Hi Yamada-san, There was recently a netfilter build error in linux-next for which a patch was posted by Taehee Yoo. The patch works (fixes the build error) but I don't see how or why. My build error report is here: https://lore.kernel.org/lkml/fa7a7824-44df-c058-dba2-ec29c5028361@xxxxxxxxxxxxx/T/#u Would you take a look at it and try to explain why the patch works? The patch's email thread begins here: https://www.spinics.net/lists/netfilter-devel/msg56985.html Thanks. -- ~Randy
