Hitting the web yesterday was the Linux 2.6.22-rc2 kernel. This release candidate contains random fixes along with architecture changes and libata and driver updates. Linus Torvalds' announcement for this kernel can be read at LWN.
The Linux 2.6.22-rc1 kernel has hit the web with almost seven thousand files changed. However, when it comes to new features in this first Linux 2.6.22 testing release are architecture updates, drivers, file-systems, networking, and a variety of other improvements. Some of the new specific improvements include a new Firewire stack, new wireless networking infrastructure, new digital video drivers, and a brand new CPU architecture. Kernel Trap has provided some additional information on this announcement.
If you've been experimenting with the idea of writing device drivers for Linux, Free Software Magazine has written an extensive article on this topic. The article starts with the differences between kernel-space and user-space components and then ends with using LEDs connected to a parallel port as the device. This how-to guide can be read here.
Interested in knowing what patches have been merged so far into the -mm kernel and will likely end up in the Linux 2.6.22 mainstream kernel? Kernel Trap has a short article and Andrew Morton's message with what is being merged in time for the Linux 2.6.22 kernel (well, so far). If you missed it, the Linux 2.6.21 kernel is now available.
It was not even a week ago that the Linux 2.6.21 kernel was released, but now the 126.96.36.199 kernel has entered the world. The first minor revision in the Linux 2.6.21 branch fixes an RT0 header IPv6 change and a fix for the netlink fib. The 188.8.131.52 change-log is available here and the source is available from Kernel.org.
After the release of the Linux 184.108.40.206 and 2.4.35-pre4 kernels earlier in the week and being two weeks since the availability of Linux 2.6.21-rc7, the Linux 2.6.21 kernel has now been officially released. The major change in Linux 2.6.21 are all of the changes in the timers and dynticks to support a tick-less kernel. Additional information on the Linux 2.6.21 kernel is available from Kernel Trap.
If you're still using the Linux 2.4 kernel, being released today is the Linux 220.127.116.11 kernel along with the 2.4.35-pre4 kernel. The day started off with the release of the Linux 18.104.22.168 and the 2.4.35-pre3 kernel, but a fib_semantics patch had broken that build resulting in a same-day re-release. The new 2.4.34 kernel contains a large amount of bug-fixes along with a small security fix. The latest 2.4.35 pre-release kernel features driver updates and other changes. As always, the latest vanilla kernel sources are available from Kernel.org. The Linux 2.6.21 kernel should be released in just a matter of days.
Kernel Trap has new coverage of the completely fair Linux scheduler. This new scheduler is currently available via a patch-set known as the "Modular Scheduler Core and Completely Fair Scheduler". This scheduling project is a complete rewrite and offers some very interesting changes. Check it out here.
If Linux 22.214.171.124 isn't your thing and you enjoy venturing into unchartered territory, Linus Torvalds has released the Linux 2.6.21-rc7 kernel. In this release candidate are mostly driver fixes along with some networking fixes and NFS changes. If some regressions can be cleared, Linus hopes to push out the Linux 2.6.21-final kernel next weekend. The Linux 2.6.21-rc7 release announcement comes today from LWN.
If you're a user of the vanilla Linux kernel, the Linux 126.96.36.199 stable kernel has been released. There's quite a few changes that make up this release and the change-log can be viewed here. Kernel downloads are available from Kernel.org.
Linus Torvalds has released the Linux 2.6.21-rc5 kernel. New in this fifth release candidate is a variety of fixes to address outstanding issues -- among architecture updates for KVM and regression fixes in other areas. Linus' announcement can be read at LWN.
KernelTrap has summarized the changes for the Linux 2.6.21-rc2 kernel. There are quite a few merges in this release that hadn't made the Linux 2.6.21-rc1 release earlier this month.
New updates are out in the Linux 2.6.18 and 2.6.19 branches. These new releases are Linux 188.8.131.52 and Linux 184.108.40.206 with information available here and here respectively.
The first release candidate in the Linux 2.6.21 kernel has been released. Among the changes in Linux 2.6.21-rc1 is the tickless kernel patch and dyntick/nohz. KernelTrap has additional coverage.
The Linux 220.127.116.11 kernel features one basic change from Linux 2.6.20... This new kernel release fixes a free-wrong-pointer bug for NFS/ACL servers. The (short) kernel mailing list message can be read here. The Linux 2.6.18 and 2.6.19 kernels have also been updated with this fix.
The Linux 2.6.20 kernel has been released. Among many other changes, new in this kernel is KVM virtualization and PlayStation 3 support. Our KVM virtualization article can be read here. The announcement and discussion on this new kernel can be read in the Phoronix Forums.
While the Linux 2.6.20-rc6 kernel was supposed to be the last test release until 2.6.20, Linus Torvalds has pushed out a seventh release candidate. This was done due to ensuring no new bugs cropped up while addressing regressions in the Linux kernel. The release announcement can be found at LKML.
The Linux 2.6.20-rc6 kernel has now been pushed out the door by Linus. Mr. Torvalds hopes that this release candidate will be the last one before the final Linux 2.6.20 release. More information is available at Kernel Trap.
A week ago Linus announced the Linux 2.6.20-rc3 kernel, and today he is pushing out the Linux 2.6.20-rc4 kernel. New in the fourth 2.6.20 release candidate is primarily fixes for Kernel-based Virtual Machine along with other fixes. The change-log is available here.
The third release candidate in the Linux 2.6.20 branch has been released today. The Linux 2.6.20-rc3 change-log covers the many changes in this release from rc2. Linus' wisdom with this release is it's always a good idea to cut a release *before* you go out to party and get drunk. Happy New Year!

Red Hat is working on engineering a new project, which they have dubbed "Stateless Linux". Some components for this project have already appeared in Rawhide. Here is Havoc Pennington's announcement.
The Linux 2.6.17 kernel has been released. In this release are quite a few changed beyond what was found in the 2.6.17 release candidates. As always, the latest kernel source is available from Kernel.org.
For your reading pleasure this weekend, CNN has conducted an interview with Linus Torvalds. Nothing too technical is asked, but it sure is an interesting read for Linux enthusiasts. This interview in its entirety can be read at CNN World Business.
Since Andrew Morton's statements last week at LinuxTag about a bug-fixing cycle for the Linux kernel, Linus Torvalds has now commented and he seems to agree on such a task. Linus does say that the 2.6.18 kernel may not hold any new features in store for Linux users, but rather may be one of the releases that targets the hunting down of bugs. More on this is here.
With two weeks since the 2.6.16 kernel was released, the first release candidate has come out for 2.6.17. Both the short and long change-logs are quite huge. Among the many changes is merged support for Sun Microsystem's Niagara architecture, and according to Linus Torvalds there is also a lot of other stuff going on with DVB re-organizations, nfs/knfsd updates, x86_64/parisc/mips/powerpc updates, ALSA, SCSI, and Infiniband. More clean-ups are also done under the hood. As always, these tarballs and other patches are available from the Linux Kernel Archives.
