Egy apró sheaf/barn változtatás a Linux 7.4-ben brutális sebességnövekedést hozott egy mérőszámban — mi történik a memóriakezeléssel, és mit jelent ez a valódi teljesítménynek? Érdekel, hogy nálad is számítana ez a változás, kipróbálnád? Olvasd el a részleteket a cikkben!

Linux 7.3 RC5 released!

After the release of Linux 7.2, which brought many features and improvements across different portions of the Linux kernel, such as hardware support and other improvements, an upcoming version of Linux is in the works.

Linux 7.3 RC5 is now live for developers and power users who are willing to try out a pre-release version of Linux that is yet to be released. All the interesting changes from performance improvements to bug fixes have been integrated to this release candidate.

The below announcement from Linus Torvalds in the mailing list says:

Another week, another large rc.

The diffstat looks a bit unusual. Less than a third of the patch is drivers, and a quarter is just selftests. Now, that's admittedly a bit misleading: most of the driver patches are rather small, and some of the selftest patches are much bigger (the biggest patch in here is the arm64 kvm ITS table test, I think). So counting the number of commits it skews quite differently. But that diffstat is still a bit unusual.

Not *bad* unusual, just not what I typically see.

The rest is mostly architecture fixes (largely kvm-related, some perf) and a fair amount of core kernel (both scheduler and bpf). And networking, of course. Most of the driver side is networking too (with drm showing up as a close second). That part is decidedly _not_ unusual.

There's various other scattered fixes in here too - core vfs, some xfs. I don't think there's any real pattern to it other than "big". But nothing looks particularly alarming, I think that despite the difftstat it's just the same old, same old.

Linux v7.3 will be the fourth version from the v7.x series that will be released after Linux 7.2, which will bring many improvements and additions to enhance your user experience.

Arch Linux and other distributions will be updated to utilize Linux 7.3 once it officially releases to the public, with rolling distros being updated first, then the subsequent distributions will utilize this version of Linux according to the distro’s release schedule. Meanwhile, keep checking for updates in your Linux distro (such as pacman -Syu as root in Arch Linux), or compile it from source.

Please note that, if you’re going to try out this pre-release version of Linux, be sure that it might contain more bugs than the final release, as it’s an experimental version not intended for production use. We advise you to back up all critical data before you utilize this version.
