SUSE developers yesterday posted their sixteen patches for implementing their kGraft live kernel patching mechanism in the mainline Linux kernel as an alternative to Ksplice. Red Hat has immediately followed-up by posting their kernel patches to Kpatch, their new approach to live patching a running Linux kernel.
The third weekly test release to the Linux 3.15 kernel is now available.
Greg Kroah-Hartman released the Linux 3.13.11 kernel this week and then called it end-of-life with the Linux 3.14 kernel now being available. However, the Ubuntu Kernel Team at Canonical has now pledged to take up the upstream maintenance of the 3.13 kernel.
Linus Torvalds just tagged the 3.15-rc2 kernel a few minutes ago in Git.
Linus pulled into the mainline Linux 3.15 kernel on Saturday afternoon a big DRM queue that contained a lot of open-source graphics driver fixes.
Now that Linux 3.15-rc1 is out, we're onto benchmarking the Linux 3.15 kernel, which brings a particularly large number of exciting changes.
Jean Delvare, a name commonly associated with the LM_Sensors project while being an employee at SUSE, has raised an important discussion item on the kernel mailing list about improving the kernel configuration (Kconfig) options when building the Linux kernel.
The first release candidate to the Linux 3.15 kernel is now available and it marks the close of the kernel merge window for about two months. Linux 3.15 is poised to be a very exciting kernel release.
There's likely just a day or two left before the Linux 3.15-rc1 kernel will be released to mark the end of the Linux 3.15 kernel merge window. With all of the major features appearing to have been merged by now, here's an overview of the exciting features to look forward to with the Linux 3.15 release.
Early on in the Linux 3.15 merge window there were improvements to significantly speed-up suspend and resume for systems, but now there's another late merge of a patch that has the capability of speeding up the resume time from suspend by 7~12x for at least some laptop/desktop systems.
For the Linux 3.15 kernel were already a lot of Btrfs bug and performance fixes, but now late into the 3.15 merge window have been some more fixes.
Experimental Linux kernel code for providing a Thunderbolt driver that works on Apple MacBook Pro systems has been updated and is still hopeful for its eventual mainline kernel inclusion.
The x86 platform driver update was pulled today for the Linux 3.15 kernel, which includes new notebook support.
For the past few years the Reiser4 file-system has mostly been in maintenance mode with there being just a handful of developers left working on the out-of-tree code, the former ReiserFS lead developer in jail, and most code activity these days just revolving around bug-fixing and adding support for newer kernel releases. However, in March the Reiser4 file-system did gain support for a new feature.
Yesterday patches were published via a pull request to enable experimental LTO support for the Linux 3.15 kernel, but Linus Torvalds hasn't yet decided whether he will accept this code in the upstream Linux kernel... Linus doesn't yet see the benefits in link-time optimizations for the kernel and isn't sure whether this code is ready yet to be mainlined.
A second staging pull was submitted for the Linux 3.15 kernel that adds the new r8723au driver for handling an increasingly used WiFi adapter common to some new notebooks/ultrabooks.
The very large DRM pull request for the Linux 3.15 kernel was submitted just moments ago with significant updates to the open-source Linux graphics drivers.
As a potentially significant performance win for the Linux kernel, when compiling the Linux kernel support for link-time optimizations (LTO) are now supported.
For those not keeping up to date on all of the Phoronix articles covering the Linux 3.15 kernel changes that landed in the past week, here's a recap of the changes that were merged so far half-way through the Linux 3.15 merge window.
Linux kernel developers have been discussing for the past few days about the possibility of encoding kernel oops messages into QR codes that would be shown on the screen.
EXT4 and XFS file-system updates for the Linux 3.15 kernel merge window are now clear.
The Linux 3.15 kernel's /dev/random implementation will feature a new instruction of Intel's upcoming Broadwell processors.
File-systems implemented via FUSE (File-Systems in User-Space) will be getting better write throughput performance when upgrading to the Linux 3.15 kernel.
Published on the Linux kernel mailing list for review on Wednesday was per-cgroup swap file support.
The Kernfs code that's a split of the sysfs logic to make it more useful to other kernel subsystems wishing to have a virtual file-system, will get better in Linux 3.15.
While the Linux 3.15 kernel is introducing a large number of new features, it's also doing away with some old drivers and older x86 platforms.
Landing a few hours ago into the drm-next code-base for merger into the Linux 3.15 kernel in the days ahead is the universal/primary plane support for the Direct Rendering Manager drivers.
There's many updates to the sound drivers within the Linux 3.15 kernel that's now officially under development.
The Btrfs file-system changes for the Linux 3.15 kernel mostly deal with bug fixes and performance fixes while some corruption fixes are also expected to come.
It was decided at last week's 2014 Linux Foundation Collaboration Summit that for inspiring a new wave of kernel developers and becoming more interactive with the community, patch review will become more social via handling patch reviews on Facebook.
