What is the reason that needs this change and only to this file? There are other
files that can do this kind of removal. Are you planning to make all the changes
also?
afaict, they are here because this file is using something defined in them. Now
it is depending on other header files implicitly including the removed headers.
#include <net/netfilter/nf_bpf_link.h>
