Why is it so desirable to do this? Reduced latency to restore at least one valid path when a bunch of paths go down? Why can't we just rely on userspace eventually figuring out which paths are failed and pushing a valid map down? Are there favorable reports that this new behavior actually helps? Please quantify how. (As an aside, really not a fan of parse_path doing what you've suggested.. will look closer once I have more justification to do so) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
