I believe a lot of people still use no-preempt. Well, at least voluntary preemption, which would have the same bug. I'm thinking that we may have just been lucky that gcc didn't move the get_user() into a place that would cause issues. Sounds like a bug to me. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
