A better solution > would be nice (lie fixing this in a merge between the net-next and net > trees). that's due to 'endif' from 290af86629b2 needs to be moved above bpf_patch_call_args() definition. There is another fixup needed for net-next. I'll send a follow up patch when net gets merged into net-next.
