With KDBUS not being called as a Linux 4.2 feature but rather being diverted with a focus on Linux 4.3, it's continuing to receive a great deal of code churn. Today it received a "big set of updates" for this controversial in-kernel IPC mechanism.
If you're a Linux enthusiast that's a habitual upgrader of the Linux kernel, you may want to hold off a few days on trying out the Linux 4.2 development kernel. For several systems, I've seen nothing but kernel panics the past few days when riding the mainline Linux kernel Git.
Right on schedule Linus Torvalds declared the first release candidate to the Linux 4.2 kernel.
One of the later pull requests for the Linux 4.2 kernel merge window is a big rework to the NTB (Non-Transparent Bridge) core code.
Yet another exciting change coming with Linux 4.2 is the start of scalability improvements for FUSE, the implementation allowing for File-Systems in User-Space.
The latest major pull request for the Linux 4.2 kernel provides the x86 platform driver updates for this next major kernel release.
Dave Chinner sent in his XFS file-system pull request today as the last of the high-profile file-system updates for the Linux 4.2 kernel merge window.
Adding to the already lengthy list of new features for Linux 4.2 is the Btrfs file-system updates that were sent in today by Facebook's Chris Mason.
With week one of two having passed for the Linux 4.2 kernel merge window, here's a look at some of the exciting new features and changes that landed in the first week.
Non-volatile memory device support will be added through libnvdimm for the Linux 4.2 kernel. Libnvdimm is a new subsystem for the Linux 4.2 kernel and contains drivers and x86 support.
For those using the Global File System 2 (GFS2) for Linux clusters, the Linux 4.2 kernel is slated to offer better performance.
While Greg Kroah-Hartman isn't sending in KDBUS for Linux 4.2 as announced yesterday, he did send in the code updates for the other kernel subsystems he maintains.
KDBUS was once again heavily debated on the Linux kernel mailing list this week and Linus Torvalds said he looked forward to merging it when ready (and also had some choice words about performance). However, Greg KH has confirmed today that KDBUS isn't ready for merging this cycle.
David Airlie has sent in the main DRM driver updates for the Linux 4.2 kernel. There's a lot of open-source graphics driver work represented by this pull request, but sadly no Nouveau (open-source NVIDIA) changes were incorporated for Linux 4.2
Ted Ts'o has sent in the big batch of EXT4 file-system updates for the Linux 4.2 kernel merge window.
Based on the native encryption support added to EXT4 with the Linux 4.1 kernel, Linux 4.2 is bringing encryption support to the F2FS file-system.
The latest subsystem update worth commenting on for the Linux 4.2 merge window are the crypto(graphy) updates with this new kernel version.
Yet another system has been added to our continuously growing basement server farm that tracks the performance of various upstream open-source projects on a daily basis. Meet system number 58!
With the new Linux kernel mailing list thread about the prospects of merging KDBUS into the mainline Linux kernel, Linus Torvalds has provided his thoughts on the matter for this controversial feature backed by systemd developers for trying to provide a high-performance, kernel-based IPC solution.
The latest pull request to be submitted for Linux 4.2 is providing a new processor architecture port.
With Linux 4.1 having been released this week and being mid-way through 2015, here's some Git development statistics for the newest kernel code.
Open-source developers for a while have been working on ACPI 6 support for Linux with 64-bit ARM support, ACPI 6 NV-DIMM support, and other functionality. With the Linux 4.2 kernel that's now in-development, more ACPI 6 code will be landing.
Alongside his many other pull requests, Ingo Molnar sent in the scheduler changes on Monday for the Linux 4.2 kernel.
Trailing last night's release of the Linux 4.1 kernel is the release of the GNU Linux-Libre 4.1 kernel via the Free Software Foundation of Latin America. This re-base against the upstream Linux 4.1 kernel takes care of "de-blobbing" more non-free areas of the open-source Linux kernel.
Jiri Kosina of SUSE has sent in the HID driver updates for the Linux 4.2 kernel and with it comes new device support.
The "x86 core" pull request for Linux 4.2 is quite hearty.
The x86 EFI changes for Linux 4.2 were mailed in this morning and indeed they offer the EFI System Resource Table support as necessary for supporting UEFI 2.5+ system firmware updates.
Waiman Long of HP has been spearheading qspinlocks now for the past several months and with Linux 4.2 the queue spinlocks support will be merged.
The Linux 4.1 kernel was released over the night by Linus Torvalds.
If all goes well, the Linux 4.1 kernel will be released before the day is over. Linux 4.1 is yet another exciting update and here's a look at some of the most prominent work found in this new kernel version.
