Greetings, and welcome!
-Starting this week’s news, The H Online have , since the 24th of March, a series of articles titled “What’s new in 2.6.34”. You can find it here: http://www.h-online.com/open/features/Linux-Kernel-2-6-34-tracking-962586.html
-Frederic Weisbecker posted perf fixes for 2.6.34, James Bottomley came up with SCSI fixes for -rc6, Paul E. McKenney had some RCU fixes for 2.6.35; perf fixes came also from Arnaldo Carvalho de Melo.
-Christoph Hellwig posted a XFS status update for April 2010; we will paste his report here in its’ entirety to let you get a clear picture : “In April 2.6.34 still was in the release candidate phase, with a hand full of XFS fixes making it into mainline. Development for the 2.6.35 merge window went ahead full steam at the same time.
While a fair amount of patches hit the development tree these were largely cleanups, with the real development activity happening on the mailing list. There was another round of patches and following discussion on the scalable busy extent tracking and delayed logging features mentioned last month. They are expected to be merged in May and queue up for the Linux 2.6.35 window. Last but not least April saw a large number of XFS fixes backported to the 2.6.32 and 2.6.33 -stable series.
In user land xfsprogs has seen few but important updates, preparing for a new release next month. The xfs_repair tool saw a fix to correctly enable the lazy superblock counters on an existing filesystem, and xfs_fsr saw updates to better deal with dynamic attribute forks. Last but not a least a port to Debian GNU/kFreeBSD9 got merged. The xfstests test suite saw two new test cases and various smaller fixes.”
-As usual, Rafael J. Wisocki announced the series of reported regressions from 2.6.33 (referring to 2.6.34-rc6-git6).
-No doubt, the most important news of this week is Linus’ announcement of 2.6.34-rc7 : “I think this is the last -rc – things have been pretty quiet on the patch front, although there’s been some rather spirited discussions.Random fixes all around, some of them RCU related (people fixing various RCU sanity check warnings), but most of them just random driver fixes. And there’s some MIPS, microblaze and ARM updates, and ocfs2 and ceph fixes. The shortlog is about as informative as anything else – nothing there stands out in my mind, it’s just a lot of small random stuff.”
-OpenSUSE’s Jiri Kosina posted HID fixes, while H. Peter Anvin posted a RFC regarding virtualization – the hypervisor layer pertaining Hyper-V and VMware code cleanups.
-Robert Richter came up with oprofile hotplug fixes for x86, sound fixes came from Takashi Iwai, perf from Arnaldo Carvalho de Melo, wireless by John W. Linville, drm fixes by Dave Airlie and networking fixes by David Miller.
-The H Online features another interesting kernel log; you can read it, along with its interesting links, here http://www.h-online.com/open/features/Kernel-Log-New-stable-kernels-and-drivers-995820.html .
-Paul McKenney posted fixes for the RCU tree (for 2.6.35, rebased for -rc7), hwmon fixes appeared courtesy of Jean Delvare, some new perf fixes by Ingo Molnar and later by Arnaldo Carvalho de Melo, tracing by Steven Rostedt, AMD iommu by Joerg Roedel, patches for the s390 series for -rc7 by Martin Schwidefsky and some perf_event fixes for powerpc by Benjamin Herrenschmidt.
-Greg Kroah-Hartman posted the “start of the stable review cycle for the 22.214.171.124 release”, stating that “There are 98 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let us 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 same Greg started the review process for 126.96.36.199, with the same message to anyone involved/interested.
-Pierre Tardy informed the community about PyTimechart by posting a RFC : “PyTimechart is another implementation of two very useful tools available for the linux community: perf-timechart ( http://blog.fenrus.org/?p=5 ) and bootchart (http://www.bootchart.org/ ) The two tools share a common idea of making their output to SVG files. While it is a very good idea for small traces, the generated SVG can be very heavy, and turns out to be good stress tests for inkscape developers…
PyTimechart is a tool that parses ftrace text traces, and display them with the help of a very powerful dynamic plot framework, Chaco (http://code.enthought.com/chaco/ ) The GUI makes the best it can to ease the browsing of huge traces.”
All in all, the respondents to this mail seemed to welcome the application as being useful.
-In the latest fixes/patches/pull requests section, we have Paul E McKenny with an RCU lockdep splat fix, Sage Weil with ceph fixes for 2.6.34-final, Frederic Weisbecker has perf/nmi fixes (uniform lockup detector), Takashi Iwai with some sound fixes; Samuel Ortiz has some MFD fixes and Steve French came up with some minor cifs fixes.
-Greg Kroah-Hartman of OpenSUSE made the announcement of the release of kernels 188.8.131.52 and 184.108.40.206 .
-Marcello Tosatti announced a series of fixes for the kvm targetting 2.6.34-rc7, Greg Kroah-Hartman posted patches for the -git kernel regarding TTY, Steven Rostedt had some tracing updates, perf fixes by Arnaldo Carvalho de Melo were posted too, and Dmitry Korokhov has fixes for the input tree.
-Mathieu Desnoyers announced the release of LTTng 0.213, with various bugfixes and improvements.
-As usual, at least lately, Michal Simek has some patches/fixes for arch/microblaze, this time for -rc8.
-Michael S. Tsirkin posted “a last minute vhost-net fix” which fixes barrier pairing.
Well, that’s it for this week’s OpenSUSE-flavoured kernel news!
I’m off, enjoy the weekend!
