When you are reading the code and you see a goto then you have to think "Oh, I wonder what the goto does?" If has a good name like "err_free_foo" then you probably can guess that it frees "foo". If it says "goto out" then you probably assume it releases a lock or something but which lock?? So then you have to jump to the bottom of the screen to find out. Once you read the bottom of the screen, you see that it is a pointless waste of time goto which doesn't do anything at all. And now you have lost your place in the code and your train of thought has been de-railed so you have to figure out where you were and what you were doing before you started on this wild goose chase. Don't do that. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
