Linux 5.14-rc1

From: Linus Torvalds
Date: Sun Jul 11 2021 - 18:50:00 EST

You all know the drill by now. It's been the usual two weeks of merge
window, and not it's closed, and 5.14-rc1 is out there.

As usual, it's much too big to post the shortlog, with about 13k
commits (an another ~800 merge commits) by about 1650 developers, and
a diffstat summary of

11859 files changed, 817707 insertions(+), 285485 deletions(-)

Appended is my mergelog which gives you an overview of what I've
pulled during the merge window, and who I pulled from. And as usual, I
want to stress how this is obviously just a very high-level summary,
and tiny part of the actual developer community - if you want the full
details of all those changes, you'll have to go to the -git tree.

On the whole, I don't think there are any huge surprises in here, and
size-wise this seems to be a pretty regular release too. Let's hope
that that translates to a nice and calm release cycle, but you never
know. Last release was big, but it was all fairly calm despite that,
so size isn't always the determining factor here..

If somebody wants to look at the actual diff for the release, I'd
encourage you to ignore - once again - another set of big AMD GPU
hardware description header files. We seem to have those fairly
regularly, and they are always these huge generated headers that end
up dwarfing everything else. Almost exactly half of the whole 5.14-rc1
patch is comprised of those GPU headers, and it skews the statistics a

Now, even if you ignore that AMD header drop, drivers account for over
two thirds of the changes when you look at the diff, and that's
perfectly normal. What's slightly less usual is how there's a lot of
line _removals_ in there, with the old IDE layer finally having met
its long-overdue demise, and all our IDE support is now based on

Of course, the fact that we removed all that legacy IDE code doesn't
mean that we had a reduction in lines over-all: a few tens of
thousands of lines of legacy code is nowhere near enough to balance
out the usual kernel growth. But it's still a nice thing to see the

So drivers dominate: even when ignoring the AMD header addition
there's a fair amount of gpu updates, but there's networking drivers,
rdma, sound, scsi, staging, media...

Outside of drivers, there's all the usual suspects: architecture
updates (arm, arm64, x86, powerpc, s390, with a smattering of other
architecture updates too) and various core kernel updates: networking,
filesystems, VM, scheduling etc. And the usual documentation and
tooling (perf and self-tests) updates.

Please do test, and we can get the whole calming-down period rolling
and hopefully get a timely final 5.14 release.
