It's probably > nothing critical. I'm thinking if we can provide UDF revision/version of UDF filesystem to userspace and looks like ID_FS_VERSION is good candidate for it... What do you think? E.g.

So for userspace this information can be useful. -- Pali Rohár pali.rohar@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
