Kernel bugs: out of control?Kernel bugs: out of control?Posted May 18, 2006 10:05 UTC (Thu) by malor (subscriber, #2973)In reply to: Kernel bugs: out of control? by arcticwolf Parent article: Kernel bugs: out of control?
It feels like you've read about three sentences of what I've written here, and you're reacting just to that. Most other replies I've put in this thread address these issues. I'd suggest reading them... I'm not going to repeat all of them here.
The strongest objection I have to the current model is that we are forced to take new features with our bugfixes, because they will not support kernels for more than two months. New features = new bugs. New bugs = new patches. New patches = new features. New features = new bugs. And so on.
'Stability', as defined from the point of view of the Linux kernel, should mean:
1) It's maintained with security patches;
In other words.... do it like 2.4 did it, after Marcelo took over. If a new network card comes out, of course you can add the driver to the source tree... it's not going to affect anyone else. If that new driver requires an update to the memory management model of the kernel, then you don't include it in the stable branch, but rather in the dev tree.
I think they might have retrofit the USB system in 2.4... it's been awhile, and I wasn't following it closely, because I didn't need to. I do know that their backports from 2.5 were done without large-scale overhauls of kernel subsystems; they kept the changes focused and very limited. And, by and large, the 2.4 kernel was very stable. It wasn't as solid as 2.2, but it was quite acceptable.
Basically, the kernel devs had the model NAILED during 2.4. This high-speed 2.6 development, on the other hand, is an absolute disaster. These guys are some of the smartest in the business, but they are still human, and they are running into the limitations of their own intelligence. The code has become too complex for them to maintain... it's hard and nasty and difficult work now, and instead of slowing down development, they're ignoring the bugs and SPEEDING UP instead, apparently because that's more fun.
It's significantly less fun for people trying to keep production machines running.
Andrew Morton is most unhappy about the quality of the kernel. That should tell you something.
