Note: We're also taking the time to obay our new .editorconfig overlord!

For a far better description of the problem than I could author, see
Jon's write-up on LWN [1] and/or Alex's on the Kernel Self Protection
Project [1].

get_maintainer.pl pulled it from here:

https://github.com/torvalds/linux/blob/master/drivers/scsi/3w-xxxx.c#L11

I like to involve the people who take the time to list themselves as
authors.  I guess these are likely to go out of date at one point or
another, especially in such a long standing subsystem such as SCSI.  Not
as big of an issue in NFC!

Oh. Hm. It seems "git check-mailmap" (and get_maintainers.pl) don't
support a way to remove an email address -- only redirect it.

It seems we may want to support "don't use this email address" for more
than just the currently observed rationale. I don't have any good
suggestions for what the format should look like? Perhaps:

"" <address-to-remove@example.com>

?
