This isn't a bug, but it looks like one adjacent blank-line pair is still
left in verifier.c. Inside the kfunc argument loop in check_kfunc_args(),
around the code that checks:
if (bpf_register_is_null(reg) && type_may_be_null(kf_arg_type))
there's a blank line pair that appears to fit the same pattern this patch
removes everywhere else. The changelog states the goal is to drop the
adjacent blank lines that have accumulated over time, and the patch removes
30 blank lines across the directory, but this one instance seems to have
been overlooked. Was that one intentionally kept, or could it be folded
into this patch so the whole directory is done in one pass?
