From:   Linus Torvalds <torvalds@...ux-foundation.org>
To:     Linux Kernel Mailing List <linux-kernel@...r.kernel.org>
Subject: Linux 5.15-rc2

So I've spent a fair amount of this week trying to sort out all the
odd warnings, and I want to particularly thank Guenter Roeck for his
work on tracking where the build failures due to -Werror come from.

Is it done? No. But on the whole I'm feeling fairly good about this
all, even if it has meant that I've been looking at some really odd
and grotty code. Who knew I'd still worry about some odd EISA driver
on alpha, after all these years? A slight change of pace ;)

The most annoying thing is probably the "fix one odd corner case,
three others rear their ugly heads". But I remain convinced that it's
all for a good cause, and that we really do want to have a clean build
even for the crazy odd cases.

We'll get there.

Anyway, I hope this release will turn more normal soon - but the rc2
week tends to be fairly quiet for me, so the fact that I then ended up
looking at reports of odd warnings-turned-errors this week wasn't too
bad.

There's obviously other fixes in here too, only a small subset of the
shortlog below is due to the warning fixes, even if that's what I've
personally been most involved with.

Go test, and keep the reports coming,

                Linus
