Yes. I know Al's thoughts and kernel style. But Alan Cox and Andreas have both said they think (x == NULL) can help you avoid some kind of boolean vs pointer bugs. I've had co-workers who did massive seds changing !foo to foo == NULL on our code base. But I've never seen a real life example of a bug this fixes. To be honest, I've never seen a real life proof that (!foo) code is less buggy. I should look through the kbuild mailbox... Hm... But my other idea of setting up code style readability testing website is also a good one. Linux kernel style is based on Joe Perches finding that 80% of the code prefers one way or the other. That's a valid method for determining code style. I bet it normally picks the more readable style but it would be interesting to measure it more formally. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
