Sort of inspired by Vasiliy's coccinelle work, I wrote a Smatch script to verify that modules unwind on errors. http://repo.or.cz/w/smatch.git/blob/HEAD:/check_unwind.c The heuristic is if you * call request_irq() * it possibly succeeded * you don't call free_irq() * you're in a function that returns an int * you are returning non-zero Then complain. One question that I had was for, "foo = request_region(bar, size)" should we call release_region() on "foo" or on "bar"? regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
