Are the following lock order reversals something that I should mention when I encounter them, in general? On the other hand, this is from an older -current, built 25.Jan, before which I don't see these messages, while after installworld/reboot, I see them, except I haven't normally booted into -current other than after -stable wedges/panics and I want to background-fsck all filesystems. Actually, it looks like once I did, so this, which immediately follows my alternate-r00t-login, is unrelated to the background fsck, but it always follows my login. If that made any sense.
