Folks,
when I took a 15-minute look at this code last week I found several bugs, some of which were grave. It's a terrible thing to say, but a sensible person would expect that a closer inspection would turn up more problems.
Now, adding bugs to existing code is fine and traditional - people find them quickly and they get fixed up.
But for *new* code, problems will take months to discover. The only practical way to get this code vetted for inclusion is a close review.
And that is a sizeable task. The core implementation file is 1,600 lines. And I wonder how many people have counted the number of comments in there?
Well, I'll make it easy: zero. Nil. Nada.
(Well, OK, a copyright header, and something which got cut-n-pasted from inode.c)
In my wildly unconventional opinion this alone makes epoll just a hack, of insufficient quality for inclusion in Linux. We *have* to stop doing this to ourselves!
epoll seems to be a good and desirable thing. To move forward I believe we need to get this code reviewed, and documented.
I can do that if you like; it will take me several weeks to get onto it. But until that is completed I would oppose inclusion of this code. - 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/
