kernel weekly news – 30.04.2011

Posted: April 30, 2011 in kernel

Hello world and welcome!

-We start with Greg Kroah Hartman and his announcement regarding
the releases of and, John W. Linville has a pull request for the wireless
tree aimed at .39, Jeff Garzik announces a round of fixes for libata and
Willy Tarreau announces the review, it is a 173-piece
patchset described by the author as following :

 This is the start of the longterm review cycle for the release.

This release is quite large, because it contains accumulated changes
from the last 2.5 months.  I spent all the day carefully reviewing 380
patches and backporting 173 of them.  I *think* the patches are OK, make
allmodconfig is happy and the code runs here, though I have only tested
x86 and x86_64.  There were a bunch of powerpc fixes that I could not
test but which applied well.  Any check on them will be appreciated.

All patches will be posted as a response to this one.  If anyone has any
issues with these being applied, please let me know.  If anyone is a
maintainer of the proper subsystem, and wants to add a Signed-off-by:
line to the patch, please respond with it.

The full quilt queue can be found at

Responses should be made within 72 hours. Anything received after that
time might be too late.

The whole patch series can be found in one patch at:
and the diffstat can be found below. 

-Martin Schwidefsky announces s390 fixes, Chris Mason has a smallish
pull request for btrfs (fixes, mostly),

-Linus Torvalds announces the release of -rc5 :

 Another week, another keyboard destroyed by spilling coffee on it..
C'est la vie.

We have slightly fewer commits than in -rc4, which is good. At the
same time, I have to berate some people for merging some dubious
regression fixes. Sadly, the "people" I have to berate is me, because
-rc5 contains what technically _is_ a regression, but it's a
performance thing, and it's a bit scary. It's the patches from Andi
(with some editing by Eric) to make it possible to do the whole RCU
pathname walk even if you have SElinux enabled.

I've been alternately kicking myself for merging it, and just being so
pleased with the rcu pathname walk now extending outside of the
no-security confines ... I dunno. The patches are all pretty simple
(there's also a few dentry cleanup patches that were the result of me
looking at profiles and generated code), and it really is a rather
important performance thing, but at the same time I would shout at
others for trying to merge it to me this late. So I'll consider myself
properly chastised.

Other than that? We should have all the fallout from the block layer
plugging changes fixed now, and Tejun fixed the infinite CD-ROM
disk-change notification thing. So that's hopefully all good and done.

And then there are all the usual driver noise (including some hwmon
documentation), some ecryptfs and gfs2 updates and just various small
random fixups. The diffstat actually looks pretty good, most of it is
just one-liners and stuff like a few new device ID's etc.

Go forth and test,


-Mauro Carvalho Chehab has media fixes for -rc5, Rafael Wysocki has two regression
fixes for the pm tree (2.6.39), James Bottomley has a parisc pull request for -rc5,
Dave Airlie has a small pull request for drm, but although small, it’s important:

 Nothing major, everyone must be on Easter holidays, the i915 one is 
actually a fix for dual-gpu laptops where i915 caused radeon to do 
something bad, the Kconfig one is because I see distros don't enable this 
and its really needed for dual-gpu functionality to work at all.

and Andi Kleen announces the release of (longterm), which
you can grab from here :

-Last-minute fresh/hot news :
-Trond Myklebust announces NFS bugfixes…

…and I’m off ’till next week. Take care, bye!
