Torvalds: User-Space File-Systems, Toys, Misguided People

Yesterday I mentioned what Anton Altaparmakov of Tuxera had recently said about their NTFS kernel driver being the fastest Linux file-system, which erupted into a large debate in our forums. Within that mailing list thread was also another interesting comment by Linus Torvalds. "Userspace filesystem? The problem is right there. Always has been. People who think that userspace filesystems are realistic for anything but toys are just misguided."

The Linux Kernel Power Issues Continues To Bite Users

The Linux kernel power regressions in the Linux 2.6.38 where I was the first to largely document and prove would cause major power problems in Ubuntu 11.04 and other Linux distributions, continues to bite plenty of mobile users.

KQ ZFS Linux Is No Longer Actively Being Worked On

Remember KQ Infotech? KQ Infotech was the Indian company that ported the ZFS file-system to Linux as an out-of-tree kernel module (after deriving the code from the LLNL ZFS Linux work) and KQ's interesting methods of engagement in our forums. The company was successful in delivering an open-source ZFS module for Linux that performed semi-well and didn't depend upon FUSE (the file-systems for user-space module) like other implementations. However, this ZFS Linux code appears to no longer be worked on by KQ Infotech.

Snapshots Support For EXT4 File-System

The Btrfs file-system has various "shiny" features like support for copy-on-write snapshots, cloning, transactions, sub-volumes, SSD optimizations, transparent LZO/Zlib compression, and many other advanced features by Linux file-system standards. The problem with Btrfs is that the next-generation file-system is still in development and hasn't yet been proven via years of use and testing yet as being a stable and reliable solution. Most Linux distributions continue using the EXT4 file-system by default, but now there may be snapshot support coming back to EXT4.

Linux 3.0-rc2 Kernel Is A Quiet Release

The second -rc release for the Linux 3.0 kernel is rather quiet and not too exciting. Linus pushed out this new kernel release in the early hours of the morning.

Linux 3.0 Kernel Has Full Support For Xen

Beyond the features of the Linux 3.0 kernel already talked about on Phoronix, there's another big milestone hit in this next kernel release beyond changing up the versioning scheme. The Linux 3.0 kernel will have full Dom0 and DomU support for Xen virtualization.

Nailing Down The Linux Kernel Power Regressions

For those that missed it, now that I've been back in the office for a few weeks and caught up on the other benchmarks and articles for May and beginning the work for June, I'm back to looking into the Linux kernel power regressions reported more than a month ago -- i.e. Linux Has Major Power Regression and Another Major Linux Power Regression Spotted.

The Linux 3.0 Kernel Will... Reboot Better?

Beyond file-system cleancache support, a Microsoft Kinect driver, Intel Ivy Bridge support, and various open-source graphics driver improvements, the Linux 3.0 kernel may also reboot your system better. Yes, really.

Say Hello To Linux 3.0; Linus Just Tagged 3.0-rc1

For anyone that was doubting Linus Torvalds would finally part ways with the Linux 2.6 kernel series, you lost your bets. On the eve of Memorial Day in the United States and his departure to Japan for LinuxCon, Linus Torvalds just tagged Linux 3.0-rc1 in Git.

CleanCache Merged Into The Linux Kernel

While the first Phoronix benchmarks of EXT4, Btrfs, and XFS on the Linux 2.6.39 kernel were just published this morning, an interesting change was just made for the next Linux kernel that will affect many of the file-systems living within the kernel. For what will be the Linux 2.6.40 kernel, or rather the Linux 3.0 kernel is the finally-merged support for CleanCache.

Linux 2.6.40/3.0 Kernel Has New Microsoft Kinect Driver

Here's another change for the Linux 3.0 Kernel (or Linux 2.6.40 if the kernel versioning change doesn't end up happening for this cycle)... Microsoft Kinect support as a new V4L kernel driver.

Linux 3.0 Kernel May Remove Some Old Cruft

The discussion surrounding Linus Torvalds' proposal to end the Linux 2.6 kernel series and continue on as the Linux 3.0 kernel has continued on since it began less than 24 hours ago. The reaction has largely been positive and supportive of this proposed change. Of the few objections, some see no reason to mess around with the versioning, but now there may be a reason for this change: to drop the old cruft that's been living in the kernel.

The DRM Pull For The Gardenshed (Linux 3.0) Kernel

While it's not known yet what the next Linux kernel will be called, right now it's looking like the next release could be the Linux 3.0 kernel. With that said, David Airlie has a pull request to go in before the merge window closes for the Linux 2.6.40/3.0 kernel. He's sent in the DRM pull request for this next kernel as the Gardenshed-rc1 kernel.

The End Of The Road For Linux 2.6 Looks Likely

It was just a few hours ago that we were the first news site to point out the message by Linus Torvalds on the kernel mailing list about his desire to end the Linux 2.6 kernel series and move future releases to the Linux 2.8 or even Linux 3.0 series. While efforts to change the Linux kernel versioning have been voiced in the past and ultimately failed, it looks like the effort this time around is building momentum and the change could very well happen.

Linus Talks Of Linux 2.8 Or Linux 3.0; Ending Linux 2.6

In a message to the Linux Kernel Mailing List today regarding the shortened merge window for the Linux 2.6.40 kernel, Linus Torvalds brings up that there's already been many Linux 2.6 kernel releases and that he could end up tagging this as the Linux 2.8.0 kernel.

What Not To Expect From The Linux 2.6.40 Kernel

Since the release of the Linux 2.6.39 kernel on Thursday, Linus Torvalds opened the merge window for the Linux 2.6.40 kernel and it will stay open until month's end. While the 2.6.40 kernel will bring several open-source graphics driver improvements (performance improvements, Intel Ivy Bridge support NVIDIA Optimus, etc), new hardware enablement, and other enhancements, there's a few features that you will not find in this next major Linux kernel release.

Linux 2.6.39 Kernel Released With New Features & Bugs

As expected to happen this week, the Linux 2.6.39 kernel has been officially released. This major kernel update provides some exciting new features and drivers, but not without some notable regressions too.

The Linux Kernel Is Still On A Power Binge

It's been about three weeks since last mentioning the major power consumption problem in the Linux kernel (actually, there's more than one power regression) and it's affecting distributions like Ubuntu 11.04. The lack of mentioning the power regression in recent weeks isn't though because the regressions are addressed, they are still outstanding with the about to be released Linux 2.6.39 kernel.

Linux 2.6.39 Kernel Is Imminent

"So things have been pretty quiet, and unless something major comes up I believe that this will be the last -rc," began Linus Torvalds in announcing the release of the Linux 2.6.39-rc7 kernel.
