Reiser4 Updated For Linux 4.14 & Introduces Zstd Compression Support

Filed under
Reiser

The out-of-tree Reiser4 file-system driver has been updated with compatibility for the latest Linux 4.14 stable series. Besides reworking the code to run on Linux 4.14, this controversial file-system has also added support for Zstd file-system compression.

Linux 4.14 introduced Zstd support in the mainline kernel and wired it in for SquashFS and Btrfs. Our Btrfs Zstd benchmarks have been promising for transparent file-system compression compared to the other supported algorithms. Reiser4 has now picked up Zstd compression as an eventual replacement to their Gzip compression support.

Reiser

For those wanting to use the Reiser4 file-system with the just-released Linux 4.13 kernel, patches are already available.

Less than one week after the release of the Linux 4.13 stable kernel, Edward Shishkin has already released an updated patch for the out-of-tree Reiser4 file-system for working with this new stable series.

Reiser4 Updated For Linux 4.12, Experimental Data Striping Support

Filed under
Reiser

Those using the Reiser4 file-system in some capacity can now safely upgrade to the Linux 4.12 kernel.

Edward Shishkin has updated this out-of-tree file-system for the Linux 4.12 kernel so it can be built with the latest mainline stable release.

Reiser4 Updated For The Linux 4.10 Kernel

Filed under
Reiser

The out-of-tree Reiser4 file-system has been updated for the Linux 4.10 kernel.

Reiser4 for the Linux 4.10.0 kernel is available as of earlier this week, managing to release their updated file-system driver code quite promptly. This port to Linux 4.10 yielded a few changes to the Reiser4 code as they re-based to this Linux kernel with the ->readlink() of inode operations being removed as well as the WRITE_FLUSH_FUA flag being removed.

Reiser4 Is Now Available For Linux 4.9, Mirror Code Almost Stable

Filed under
Reiser

For those that haven't yet switched to Btrfs, ZFS On Linux, or running EXT4/XFS but holding out hope for Reiser4, this out-of-tree file-system code has been updated for Linux 4.9.

Reiser4 was released for Linux 4.9.0 last weekend but then a revised patch series came out three days ago to fix some problems with this port to 4.9. With the new Reiser4 patches built against Linux 4.9.1, all should be well if you want to use this experimental file-system on the newest Linux kernel.

Reiser4 Now Available For Linux 4.8 Kernel

Filed under
Reiser

While Linux 4.9 will be released in just a few weeks, the remaining Reiser4 file-system developers have just updated their code to support the Linux 4.8 stable kernel.

Reiser4 for Linux 4.8.0 is now available for those wanting to run this out-of-tree file-system on the current stable kernel. The Reiser4 kernel is now compatible with 4.8 and there is also a kernel oops fix when mounting forward-incompatible volumes, unneeded assertions were removed, some VFS changes were made, and there is now rename2 support.

Reiser4 Implements Mirror & Failover Support

Filed under
Reiser

Edward Shishkin, one of the last remaining Reiser4 developers and the one who has been leading this out-of-tree file-system the past few years, has implemented logical volumes support with support for mirrors (in effect, RAID 0) and failover support at the file-system level.

Shishkin quietly announced on Sunday, "Reiser4 will support logical (compound) volumes. For now we have implemented the simplest ones - mirrors. As a supplement to existing checksums it will provide a failover - an important feature, which will reduce number of cases when your volume needs to be repaired by fsck."

Reiser4 Now Has Support For The Linux 4.7 Kernel

Filed under
Reiser

The Reiser4 file-system now has support for the latest stable Linux kernel series, Linux 4.7.

Released this morning by Edward Shishkin was the updated Reiser4 file-system driver patch that provides compatibility for Linux 4.7.0. The only other change besides porting over to Linux 4.7 is a small returned optimization.

There's been no talk in a few years about attempting to mainline the Reiser4 file-system in the Linux kernel. Thus for now if you want to try out this once-promising file-system, swing by SourceForge to patch your kernel.

  • My assessment of “btrfs”

    In short: Novelist Stephen Elliott (James Franco) find himself drawn to the high-profile Hans Reiser (Christian Slater) murder trial - a case that brings him closer to his own troubled past with father (Ed Harris). Amber Heard, Wilmer Valderrama and Cynthia Nixon also star. (Watch the trailer)

  • The Adderall Diaries

    While Romanowsky gamely tries to negotiate the same structural tricks as the book, which employed the Reiser case as a base camp from which the author could depart and return, in the film it feels more like a subplot despite the cinematic tricks -- the cross-cutting and slo-mo flashbacks -- that the director uses to try to connect the stories. At times it feels flat, other times risible, and only occasionally do the stories resonate in any kind of harmony.

  • My assessment of “btrfs”

    Short version — I will continue to use “ext4” in future installs.

    Note that this a personal view, not a recommendation. My own choice depends on how I use computers and my practices for backup, recovery, etc. Your practices are likely different. Much of this post will be about my considerations in deciding against “btrfs” for my own use.

Reiser4 Now Available For Linux 4.5 Kernel

Filed under
Reiser

The Reiser4 file-system has been updated with support for the Linux 4.5 kernel.

Edward Shishkin, the main Reiser4 developer left working on this out-of-tree file-system, today spun the Reiser4 patches for the Linux 4.5 kernel that also includes a few fixes/changes for satisfying the kernel and compiler. Aside from that, there's nothing new to report today with regard to new Reiser4 file-system features nor any new attempt to try to mainline this file-system code.

  • CSR devices now supported in fwupd
    The BlueCore CSR chips are used everywhere. If you have a “wireless” speaker or headphones that uses Bluetooth there is a high probability that it’s using a CSR chip inside. This makes the addition of CSR support into fwupd a big deal to access a lot of vendors. It’s a lot easier to say “just upload firmware” rather than “you have to write code” so I think it’s useful to have done this work.

    Imagine a scenario where a programmer needs to follow a couple of tried and tested procedures to write code that becomes a part of a bigger program that needs some insightful contribution from another programmer. So, is the first programmer really needed? Can’t we find a robotic replacement for the same? In the past, GitHub CEO had already made a prediction which says that future of coding is no coding at all. A similar speculation has been made by the researchers at the Oak Ridge National Laboratory, Tennessee, who have said that machines will write most of their own code by 2040.
