This is one of those "impossible condition has been met" messages. Essentially
it means that we got a lookup call for a mountpount,
which should not happen because it's a mountpoint, so it's always valid and
pinned in memory at the very least.
What kernel do you use? anything else interesting about this client - e.g. NFS
rexport?
