Linux 3.18-rc6 Released, A Worrisome Regression Remains

It was maintained for a few years.

Yeah, but i guess they just sorted manally those from bugzilla and made a list out if it

Would the Linux kernel have less bugs if it were ported from C to Rust?

Which bugs, there is no bug in Linux

He, he, funny answer - but true Linux only have bugs, because it progressing all the time, so by making any progress naturally you intruduce new bugs, doing any new work you have new bugs, etc... Porting to different language, yeah you will have new bugs likely and so on...

Compare that with life... that is like whatever you do in your life and for your life, you made new problems for other peoples and might be also for you - sometimes even without knowing. Those might be nice or worst for some of them, but those are new problems, bugs

less bugs? who knows that might depend on porters On human, not on language.

Is it possible that this happen so commonly!?

Is it possible that this happen so commonly!?

Mostly no, but can happen anytime



It is normal in kernel development

FYI, I gave 3.17 + perf fixes ~36 hours of runtime before calling it
good on Friday. Since then I've started a bisect, and I'm about 3 builds
deep on that, with 9-10 to go. 2 of the bad builds took the better part
of a day to hit, with the third happening in just an hour.
Hopefully I get more of the latter kind, and we can wrap this up this
week, though thanksgiving may upset things.

Would the Linux kernel have less bugs if it were ported from C to Rust?

No, because any complex project that is ported to anything inevitably creates new bugs. That's the nature of writing complex new code.

Now, if you change the question to whether there would be fewer new bugs created on an ongoing basis, that's more interesting. Probably not much difference in the end, though, because all the kernel devs would be turning off the safety features in rust anyway.
