Guest Blog: Rares Aioanei – Weekly Kernel Review (openSUSE Flavor)

June 26th, 2010 by

Hi everyone, and welcome to this week’s edition! As usual, new commits, patches and fixes are waiting, so let’s dive in!

-Karel Zak announced the release of util-linux-ng v 2.18-rc2, available at ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/v2.18/ ; a changelog is also available in the announcement.

-Matthieu Desnoyers announced Userspace RCU 0.4.6 with the following (short) announcement text : “I just released userspace rcu 0.4.6, which contains added ARMv7l support. It also includes the new make check target. I skipped 0.4.5 because I updated the README file after the release.”

-Jeffrey Merkey announced Open Cworthy 6-19-2010 x86_64 fixes with the following changes : “Fixed NWSCREEN pointer size mismatch on x86_64

Fixed build problems on x86_64
Fixed Memory Overwrite glibc message on Fedora 13 x86_64
Upgraded memset and memcpy functions for x86_64

Tested on a 4 processor opteron HP Proliant running Fedora Core 13 x86_64 and FC8 ia32”

-Jean Delvare pushed hwmon fixes for Linus, targetting 2.6.35, Jesse Barnes comitted  a fix for the PCI tree (for -rc3), Paul Mundt posted a pull request to Linus regarding sh updates for -rc4 and John W. Linville posted his pull request regarding the wireless tree (22.06.2010), with just one fix. As some of you may already know, Linus is in a vacation, so the number of git pull requests is smaller than usual.

-Matthieu Desnoyers made an announcement pertaining to the release of LTTng 0.217 for 2.6.34, describing the update as follows : “LTTng 0.218 adds a missing irq_desc export in kernel/irq/handle.c, which only affects sparse irq configurations. This omission only appeared in 0.217.”

-Henrik Rydberg announced the release of mtdev 1.0.1, explained as “mtdev – Multitouch Protocol Translation Library (MIT license)

The mtdev library is a kernel input event stream translator, which greatly simplifies multitouch handling in applications. The input events are simply routed through mtdev, which transforms them to a uniform stream of MT slot events. Software finger tracking is performed when needed, making all devices appear as if they had tracking capabilities. For further details and the source git tree, see


The bulk of mtdev has been around since 2008, as part of the Multitouch X Driver project (http://bitmath.org/code/multitouch/). By releasing mtdev as a stand-alone package under the free MIT (X11) license, we hope to simplify the adoption of the MT event protocol in applications.”

-Rafael J. Wysocki posted the list of reported regressions from 2.6.34 related to 2.6.35-rc3, as well as a list of reported regressions between 2.6.33 and 2.6.34.

-The H Online published an article titled “Linus resolves to apply a strict policy over merging changes”,  with the following headline : “It would appear that Linus Torvalds has resolved to apply a strict policy of accepting only bug fix changes to the kernel after the merge window has closed. Torvalds has also stuck his oar into the debate over the Android suspend block API and made the situation even more complicated.”

-Rusty Russell published few virtio fixes targetted at -rc3, Steven Rostedt posted a pull request for Ingo Molnar related to the tracing tree, and that’s about it for this week, a week with shorter news and no rc, nevertheless with some interesting points worth reading.

Have a great weekend! See y’all next week!
