if you do: % cd /nfsdir % mkdir -p foo/foo % mv foo/foo . nfs_sillyrename() self-destructs if you try to sillyrename a directory, however nfs_rename() can be coerced into doing just that by the above sequence of commands. To avoid this, nfs_rename() now checks that v_type of the 'destination' vnode != VDIR before attempting the sillyrename. The server correctly handles this particular situation by returning ENOTEMPTY on the rename() attempt. I asked if this was the correct fix for this on -hackers but nobody ever answered. This is a 2.2 candidate.
