kernel news – 15.10.2012

Posted: October 15, 2012 in kernel

-Here’s the announcement of 3.7-rc1:

The two weeks are up, and I was merging during my trip, so no reason
for merge window extensions.

The 3.7-rc1 kernel is out there. There’s a few big things worth noting here:

– the “uapi” include file cleanups. The idea is that the stuff
exported to user space should now be found under include/uapi and
arch/$(ARCH)/include/uapi.

Let’s hope it actually works. Because otherwise this was just a
totally pointless pain in the *ss. And regardless, I’m definitely done
with these kinds of “let’s do massive cleanup of the include files”
forever.

– arm64 architecture inclusion. Let’s see if it takes off..

… and let’s see how many years we’ll need before the arm people
do what every single other 64-bit arch has ever done: merge back with
the 32-bit code. As usual, people claimed that there were tons of
reasons why *this* time was different, and as usual it’s almost
certainly going to be BS in the end, and a few years from now we’ll
have big patches trying to merge it all back. But maybe it really
*was* different this time. Snicker.

– arm multiplatform code.

Finally. The ARM devicetree code stuff etc means that at least some
arm kernels can now be built to support multiple different platforms
in one single binary. I’m sure there’s still tons to go, but it’s a
big milestone nonetheless.

– ARM virtualization and Xen support.

– user namespaces are coming back in a workable form.

– signed kernel modules

– nice cleanups: workqueues (Tejun Heo) and generic
execve/kernel_thread (Al Viro)

There are tons of other updates, but those are the “big new features”
that came to mind. Maybe I missed some.

Of course, despite all the above changes, the bulk of the actual
patches are still the usual driver updates, which aren’t even
mentioned above. So the “big changes” are actually in reality smaller
than the “normal changes we have all the time”.

Anyway, the shortlog is much too big as usual for an -rc1 (with over
ten thousand commits), but appended is my “short mergelog” that gives
at least some high-level view of the merges I did.
