Subject: Linux 2.6.33-rc2 - Merry Christmas ...

.. or wahetever it is you'll be celebrating today/tomorrow.

And if you aren't celebrating anything at all, but instead sitting in your
dark basement feeling lonely and bored, you can at least try out the
latest -rc kernel. Because it's better than moping around doing nothing.

And if you _are_ celebrating, but are having a bit of an overload of ham
(or are getting fed up with losing all your clothes in strip dreidel and
having people point and snigger at you, if that's what gets you through
the holidays), take a break, compile a kernel, and try it out for size.

Because while your pants may not fit you for the next month, the new
kernel might just fit your computer perfectly.

The dirstat says it all: mostly drivers (much of it staging updates,
especially as nouveau also counts as staging even if it's not physically
there). But a smattering of changes all over (scheduler, vfs, arch, kfifo
etc):

2.9% Documentation/
2.4% arch/arm/
3.4% arch/powerpc/
2.7% arch/x86/
9.4% arch/
9.8% drivers/gpu/drm/nouveau/
2.8% drivers/gpu/drm/radeon/
15.4% drivers/gpu/drm/
6.4% drivers/platform/x86/
12.1% drivers/staging/dst/
13.4% drivers/staging/sm7xx/
27.1% drivers/staging/
10.3% drivers/usb/serial/
11.9% drivers/usb/
69.3% drivers/
3.7% fs/
6.4% include/linux/
6.5% include/
3.4% kernel/
2.4% sound/pci/hda/
3.3% sound/

I'd have been happier with a smaller -rc2, but I've seen worse too, so I'm
not going to complain.

And now I'm off to peel potatoes. And then to eat them.

Have fun,

Linus

Hmm, the patch is busted in one way, but it should not be crashing like
that still... I wonder what is going on. Still, the patch below should
help it a bit.

dell-wmi - fix condition to abort driver loading

From: Dmitry Torokhov <[email protected]>

The commit 1fdd407f4e3f2ecb453954cbebb6c22491c61853 incorrectly made driver
abort loading when known GUID is present when it should have done exactly
the opposite.

Unfortunately, it is not a false positive, as removing a PCMCIA device
racing with "pccardctl eject" seems to trigger this path as well. Patch is
being prepared...
