For those of you wondering the performance impact of using mount options for tuning the Btrfs file-system on the soon-to-be-out Linux 3.9 kernel, here's some benchmarks of common Btrfs mount options.
PKSM is a new system memory de-duplication method for the Linux kernel that was developed after seeing the current KSM and UKSM approaches as being ineffective.
The Linux 3.7 kernel brought ARM multi-platform support and now with the Linux 3.10 kernel it may be extended to support the Samsung Exynos SoC family.
The Linux kernel is having to remove support for NWFPE and VFP emulation code due to a licensing conflict. Removing NWFPE and VFP from the kernel will effectively render older ARM hardware on Linux useless until a solution is determined.
While some patches have turned up in the past, the mainline Linux kernel has yet to have support for Apple's infrared remote control found on their computers since 2005. Fortunately, it looks like a new Apple IR driver is taking shape.
One of the areas of hardware power management that can yield a surprising amount of power-savings but is often overlooked comes down to the system memory. Fortunately, new Linux kernel patches continue to be written for improving the Linux kernel RAM power management.
Red Hat's Mikulas Patocka has posted a set of Linux kernel patches that parallelize the dm-crypt sub-system.
Samsung developers last week provided patches for a new cpufreq governor dubbed "LAB", or the "Legacy Application Boost", for the Linux kernel.
The Linux 3.9-rc6 kernel was released over the night. With Linus expecting next week's 3.9-rc7 kernel to be the last test release, the final release of the Linux 3.9 kernel is expected in about two weeks time.
The Linux kernel has been ported to the Texas Instruments TI-Nspire. The TI-Nspire series platform powers higher-end graphing calculators in recent years from the Dallas-based company.
A few months back there was an EXT4 file-system corruption bug that impacted stable Linux kernel releases and was widely-covered. Today, another EXT4 file-system bug was corrected within the mainline Linux kernel.
Linus Torvalds released Linux 3.9-rc5 on Easter. This kernel midway through the Linux 3.9 kernel cycle isn't particularly thrilling but does provide fixes for new features.
The Sun/Oracle ZFS file-system port to the Linux kernel has now been deemed ready with its new release as "ready for wide scale deployment on everything from desktops to super computers." Will you use ZFS On Linux?
Linus Torvalds announced the release of the RC4 for the Linux 3.9 kernel on Saturday evening, but its development still has not slowed down.
Is the Tux3 file-system alive and well for Linux or will it face a fate like Reiser4 where it may never see a mainline state?
Linus Torvalds put out the Linux 3.9-rc3 kernel on Sunday afternoon.
Introduced to the world on Monday and already revised today is the Linux Kernel Wait-Free Concurrent Queue Implementation.
The Overlay File-System has been in development for several years and is used by some notable Linux distributions, but has yet to be merged into the mainline Linux kernel after having to be pulled a few times in the past. The new plan is to merge OverlayFS for the Linux 3.10 kernel.
The second release candidate to the Linux 3.9 kernel is now available. Standing out in this week's kernel development update is work on WiFi drivers and other updates throughout kernel-land.
While there are many interesting features to the Linux 3.9 kernel, there is some functionality you will not find yet within the mainline Linux kernel.
Progress is being made within the Linux kernel for reducing the I/O wait times and system interactivity/responsiveness when dealing with large I/O operations.
Linus Torvalds released the first release candidate for the Linux 3.9 kernel on Sunday afternoon. He says with this kernel there's changes all over the place, but the merge window was a bit rocky but fortunately with all of the nasty bugs "each time people were on them like paparazzi on Justin Bieber."
In addition to the already exciting features of the Linux 3.9 kernel, this next release will also bring several new features to the Btrfs file-system.
Aside from Google Zopfli there is some more Linux/open-source compression algorithm news today. The LZO compression/decompression support within the Linux kernel has been updated against upstream. LZO in Linux 3.9 will now be much faster.
The merge window for the Linux 3.9 kernel is coming to a close and most of the major merges have already occurred, so let's take a look at some of the best new features coming to this next Linux kernel release.
The EXT4 file-system in the forthcoming Linux 3.9 kernel will support using the previously-introduced punch hole functionality for inodes not using extent maps.
The DRM pull request for the new features to be introduced in the Linux 3.9 kernel have been presented.
A Linux kernel exploit was made public this weekend that affects versions of Linux going back to the 3.3 kernel. This exploit allows for user-space programs to gain root access through a bug in the kernel's networking code.
Samsung developers have worked up a set of improvements to the new F2FS file-system for the Linux kernel. The F2FS work in Linux 3.9 mostly comes down to fixing issues with the Flash-Friendly File-System and implementing some new functionality.
The PCI pull request for the Linux 3.9 kernel reveals that more hot-plugging work is about to land plus developers are still working on the handling of PCI Express ASPM (Active State Power Management), the cause of the major Linux kernel power regression of 2011.
