Well, the first thing that needs to be done is a full review of every user and fixes applied. The second thing is that we need eyes on code _and_ review comments, and educate those who are telling people to use IS_ERR_OR_NULL() whenever they see an IS_ERR() to think about the code a little more - that's kind of the purpose of my email. Unfortunately, it's going to take time to achieve a change, and if I end up being the only one who's spotting these errors, I'm going to get incredibly pissed off at doing so (because it will feel like I'm being ignored when there's a constant stream of it.) Another thing would be to work out whether we can get checkpatch to detect usage of IS_ERR_OR_NULL(p) followed by PTR_ERR(p) without any explicit NULL checks against p in the same block. That's probably going to be interesting to code up in perl. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
