I wonder who is supposed to apply this patch. Either it should be split
by file and go in via the respective maintainers, or it goes in via

It should be split up into each subsystem patch and submitted that way.

We also need a "real name" here that is used to sign legal documents. I
doubt an all-lower-case name is used that way, so I have to ask.
