You either have to check the logs, or run fsck before mounting the file system. It really seems like a optimal thing to provide a way to inform user space about this without the need to parse the log. I think that sysfs is a perfect place for this. However we might to go a step further, because I do not really like the idea of allowing to mount the file system with errors by default. It does not really make sense to me and I wonder whether someone actually intend to do it this way. What about having this scenario respect "errors=" setting ? Of course it might not make sense to panic when mounting file system with errors with "errors=panic" option, we can just fail the mount. Will that help your case ?
