Similar comment to the last one. :) I suspect the issues you are seeing are largely new due to the ref-paranoia work I did (merged in 05e816e37). We used to ignore broken refs at the for_each_ref() level, but now we feed them to the calling code (which generally chokes). So in that sense, a simpler fix than your series would be to simply revert 8d42299 and ff4056bbc. :) But I think those new checks are valuable, and we really just need to gracefully ignore the dangling-symref case (which is _a_ breakage, but not a dangerous one). -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
