Is it possible to check that which header files are included in source
file.

I mean how many header files are included for kernel/module.c and in
which order and we can also check that same file is requested how many
times, like:

	linux/module.h (requested count, included or not)
	+linux/list.h
	++linux/stddef.h

and so on.
