submitting-patches.rst says:

        On the other hand, if you make a single change to numerous files,
        group those changes into a single patch.  Thus a single logical change
        is contained within a single patch.

Also refer 96d4f267e40f9 ("Remove 'type' argument from access_ok() functioin.")
