Linux might no longer support HFS/HFS+

The antique filesystems, HFS and HFS+, were used in old Macs going back to Septmber 17th, 1985, with the former being used first, then the latter. They also have alternative names, called Mac OS Standard and Mac OS Extended.

During development of Mac OS X 10.6 Snow Leopard released in August 28th, 2009, Apple decided to stop all support for read-write HFS and HFS+ filesystems, making users be unable to write to any file, but they still could read from such volumes. In macOS Catalina, Apple finally removed the filesystem support from the Darwin kernel, making it impossible to use disks that are still formatted with such filesystems.

We appear to have reached the end of support for the two antique filesystems in Linux, too, because, this year, the prominent Linux developer from Microsoft stated that, via Mastodon:

Let’s try and remove #hfs and #hfsplus by the end of 2025. They have been orphaned since 2014 and are turning into a maintenance burden.

If you’re still using those filesystems after the support ending period, there is a chance that you could use those filesystems again via user-space filesystems, except that you won’t have the same experience, including the lack of support of writing to files for HFS+.

Linux 6.15 RC2 released!

Linux 6.15 RC2 has been released for developers and curious users to try out. All the interesting changes from performance improvements to bug fixes. Spectre RSB mitigation cleanups for AMD and Intel processors, various graphics driver fixes, and all other important fixes for different kernel components.

In the release announcement for this version of the kernel, Linus Torvalds said:

It's Sunday, just barely afternoon, and I've pushed out the rc2 tag.

Things look fairly normal. Yes, this was a larger-than-usual merge window, but at least for now rc2 looks pretty much in line with normal statistics both when it comes to number of commits and to the diffstat. Nothing particularly stands out to me, but it's early in the release yet, so let's see how it goes...

About a quarter of the patch is selftests updates, which is perhaps a bit unusual but at the same time certainly not alarming.

Other than that, it's all pretty evenly spread out: drivers (gpu is about half of that), arch updates, core kernel and networking,
filesystems, documentation. A little something for everybody, in other words.

Why not try out this awesome pre-release of Linux 6.15?
