Future feature? For now though, the `btrfs check` message lacks an indication of the (un)seriousness of the problem, or what the user should do about it. Maybe this message could be prefaced with INFO: ? to suggest it's just an informational level concern? The problem with the message and documentation is users are being advised to ask a btrfs developer or expert what to do about this message. So I kinda expect there will be messages on this list from users asking about it. --- Chris Murphy
