Currently checkpatch warns when asm/file.h is included and linux/file.h
exists. That conversion can be made when linux/file.h includes asm/file.h
which is not always the case.(See signal.h)

This won't work with #include forms like:
#include <asm/foo.h>
or when checkpatch is run from somewhere other
than the top of tree.
why the -i?

This was just an RFC. I guess you're ok with the idea so I added your
