Script I use is much simpler.

#! /bin/bash
# script to copy sanitized kernel headers

if [ $# -ne 1 ]; then
   echo "Usage: $0 kernel-directory"
   exit 1
fi

SRC=$1
if [ ! -r $SRC/usr/include/linux/rtnetlink.h ]; then
   echo "$SRC is missing headers"
   exit 1
fi

if [ ! -r include/uapi/linux/rtnetlink.h ]; then
    echo "$PWD is not iproute2 source"
    exit 1
fi

for subdir in . rdma vdpa
do	   
    DST=$subdir/include/uapi
    echo Checking $DST

    (cd $DST; find . -type f) | \
	while read f
	do
	    from=$SRC/usr/include/$f
	    to=$DST/$f
	    if ! cmp -s $from $to
	    then
		echo Updating $f
		cp $from $to
	    fi
	done
done
