Yeah, the callsite I had intended ended up needing to save it across more than just error(). And I think that is probably why we have never done any errno-handling inside error() before (it is certainly not the first time I thought of doing such a thing): real-world cases tend to be a little more complicated. That being said, if this copy() case is one that could benefit, I do not have any problem with picking up (or just reusing the concept of) my 1/4 from that series. It probably does not _hurt_ anything, and if it can help in even a few cases, it may be worth it. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
