Hello, everyone, and welcome!

This week sees the release of 2.6.35-rc1,  plus other kernel-related news, so let’s start.

-Along with tree updates/patches/fixes for the usually/most updated trees,  such as perf, x86, tracing or infiniband, for example, Linus Torvalds announced the release of 2.6.35-rc1 : “It’s been two weeks, and so the merge window is closed. There may be a few trees I haven’t pulled yet, but the bulk should all be there. And please, let’s try to make the merge window mean something this time – don’t send  me any new pull request unless they are for real regressions or for major bugs, ok?

This time, there are no new filesystems (surprise surprise), but there’s certainly been filesystem work both on an individual FS layer (btrfs, cept, cifs, ext4, nfs, ocfs2 and xfs) and at the VFS layer (superblock
and quota cleanups in particular).

But as usual, the bulk of the changes are in drivers. About two thirds of all the changes, to be exact. infiniband, networking and staging drivers are the bulk of it, but there’s changes all over (drm, sound, media, usb,
input layer, you name it).

And what’s good to see is that we continue to have very healthy statistics. About 8500 commits (of which 400+ are merges), with about a thousand individual developers involved (git counts 1047, but some of them are bound to be duplicates due to people mis-spelling their names etc).
It’s skewed, of course – with the median number of commits per person being just three – but I think that’s what we want to see in a healthy development environment.

-Greg Kroah-Hartman announced 2.6.32.15, and his description says much in very few words : “It reverts two patches that were previously applied that shouldn’t have been in the .32 kernel series.  If you don’t have any problems with the 2.6.34.14 kernel, there’s no need to upgrade to this release.”

-The H Online has an interesting article named “Kernel Log: Linux 2.6.35 taking shape”. In a few words, the article is about “Linux 2.6.35 will deliver better network throughput,  support the Turbo Core functionality offered by the latest AMD processors and de-fragment memory as required. On LKML, a discussion on merging several patches developed by Google for Android is  generating large volumes of email.” Have a read here : http://www.h-online.com/open/features/Kernel-Log-Linux-2-6-35-taking-shape-1012850.html if you’re interested.

-Eric Anholt came up with improvements and fixes in the drm-intel tree destined for -rc1, including h264 acceleration for Ironlake hardware, Benjamin Herrenschmidt updated the powerpc tree, Konrad Rzeszutek Wilk added some features to the iBFT tree for -rc1, Jeff Garzik had some minor fixes for the libata-dev tree and Arnaldo Carvalho de Melo posted a series of improvements for the perf tree targeted at 2.6.36.

-Jeffrey Merkey announced the Cworthy libraries for Linux kernel utils : “I created a cworthy library under ncurses for xterm and linux terminals (also works on DOS and Windows too) years back and have ported it to .so an .a formats.  Looks like the old NetWare inderface and runs on Linux terminals.  Wrote a sample IFCONFIG lookalike with the cworthy look alike portal manager that displays the same info as IFCONFIG.  May be of use and looks a lot better than the command line. It is not the actual cworthy but recreates the same look and feel and supports all the colors you would want with all the fancy menu and screen functions.  I donate it to make the kernel utils look better and make me feel more at home since NetWare is no more.  I use this lib in most of my projects and it was included in the old NWFS but was not cleaned up and broken out.  I pthread enabled it and also added support for most of the terminals our there (ANSI and dumb not supported but the rest are).”

-Speaking of the perf tree, Frederic Weisbecker and Ingo Molnar also posted fixes in this area, while Paul Mundt updated the sh tree for -rc2; Steven Rostedt posted a fix related to tracing, Dmitry Torokhov updated the input tree for -rc1 and Robert Richter fixed crashes and other improvements in the oprofile tree.

This concludes this week’s Weekly Kernel News. Have a lot of fun.
