Most servers are most likely on LTS distros and won’t be affected by this bug.
Interestingly it seems the first rule of kernel development, we don’t break user space should apply here.
I'm not a kernel developer, but it does seem weird to remove the legacy function in the same patch as the replacement function is shipped.
That said, isn't it fairly easy to install a modified kernel? Or is that hard on Ubuntu for some reason? I suppose it's to do with official support cycles and patches, so that's only really a viable fix if the distro manages to kernel options, to ensure timelines with security patches and commercial support.
yeah i'm running a lts distro but keep the kernel up to date, it's super simple, there's even gui apps for it
That's the thing. It doesn't break it to the point of unusable unlike other patches I think. So the test didn't catch this since performance is rarely a part of a test suite no?
First thing you need to know. There's nothing special about at Linux x.0 release. It's just the next one.
I'm suddenly seeing a lot of posts about kernel 7.0...
There is nothing more special about 7.0 vs 6.19 or 6.18
Going from 6.x to 7.x doesnt mean new features or anything special
I suggest reading the first paragraph, it addresses your point.
aren't kernel versions literally vibes based? i recall hearing that Linus just declares a new major version when it feels right.
In recent history, it's every 20 versions, iirc: 5.19, 6.0, ... , 6.19, 7.0
4.20 though, because reasons.
Dang. Some nice stuff in this one.
That stutter they mentioned, while I find it infinitely less common than similar stutters in Windows, will be super lovely to be rid of. Very nice.
Does the major version number (4.x vs 5.x) mean anything?
No. The major version number is incremented when the number after the dot starts looking "too big." There is literally no other reason.

Also,
Does the odd-even number still mean anything?
A long time ago Linux used a system where odd numbers after the first dot indicated pre-release, development kernels (e.g. 2.1, 2.3, 2.5). This scheme was abandoned after the release of kernel 2.6 and these days pre-release kernels are indicated with "-rc".
(RSEQ) ... you should notice smoother multitasking, and a more responsive desktop when your system is under load.
That's neat. I wonder if it is actually noticeable during average use. It would also be amusing if this caused some novel bugs hehe.
Also I would still rather no illustrations than what are obviously slopped up oversmooth tux pix. Or even just crude line drawings would look more appealing...
