Subject[PATCH] bpfilter: remove extra header search paths for bpfilter_umh
Currently, the header search paths -Itools/include and
-Itools/include/uapi are not used. Let's drop the unused code.

We can remove -I. too by fixing up one C file.

Signed-off-by: Masahiro Yamada <>

Perhaps, are these extra header search paths for
more upstreaming in the future?

If this patch is rejected, I will send an alternative one.

To clean up the Kbuild core,
I want to drop as many unused header search paths as possible.
