First is that naming is important if people are to understand the release system, and I think a lot of people don't. So why not: - put out -devN kernel for testing, lots of people don't know about -bk or how to patch. And have the changelog list only the major new features and bug fixes, no author, no date, just a list of the important changes. That means that the user can see, not internal performance tuning and such. - call the first rc -rc0, which indicates that only bug fixes from this point on, and the level of stability (no much). I think about rc1 people would be more willing to test, and if I have a problem and the -dev claims a solution, I would be more willing to test, which might catch more of the "this crap doesn't even compile" errors. > So let's loook at how we could set that up.

Two big screenfuls (or four, > for people who still use the ISO-ANSI standard 80x24 vt100) It's your ruleset, but I think the next rule is adequate. If there's a serious problem, and the solution means fixing bad locking in 50 places easily identified, it's probably still worth fixing if there's no band-aid available. In short, trust the maintainer to make a good call on this. > > Also, I'd suggest that a _hard_ rule (ie nobody can override it) would > also be that the problem causes an oops, a hang, or a real security > problem that somebody can come up with an exploit for (ie no "there > could be a two-instruction race" crap.

Way overkill, if the maintainer can be trusted to either understand or pass the vetting to someone who does, more eyes increase the probability if someone rejecting a valid patch because they didn't understand it. > > Again, this is really to protect the sucker, and make it possible to > work: I don't think this can work with a creative person (everybody > else calls me "flaky", and I much prefer that "creative" word, it sounds > so much better), which I personally believe means that we don't _want_ > people like Alan, Andrea, Andrew etc etc that have historically maintained > their own trees that sometimes have tried to do something like this.

(I wrote "happy" rather > than "happier" at first, but let's face it, people are better at whining > than they are at being happy ;) I think this is just what's needed, and it addresses both the delay in getting new features in as well as delay in getting fixes in a stable kernel. -- -bill davidsen (davidsen@tmr.com) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
