I really would prefer if you just figured out your email settings so
this isn't needed. The From: header is mostly used for people
forwarding patches from other people. We have allowed people to use
the From header like this if they can't get their corporate email
configured properly but I try to discorage it. If everyone starts using

This patch is much better and more interesting, but I still want some
more changes.

In the kernel we don't put code in until we are ready to use it. Don't
worry about future changes. But on the other hand, don't remove the
parameters in this patch because that is doing too many changes in one
patch. It would have to be done in a follow on patch if you decide to
do it.

Just remove this function. But mention it in the changelog in case
there are side effects.

Don't put obvious comments like this. A normal reader will assume that
this function is boolean based on how it is used.

Don't put the == 1. In terms of English, 1 really is intended as
"success" and not the number one. Also don't test for == true or
== false.
if (foo) {
if (foo == true) {
These two statement *mean* the same thing in terms of English, but the
first one is simpler and less wordy.
