FWIW, I'm trying to track down exactly the same warning on a RHEL6.2 kernel being triggered by NFS filehandle lookup. The problem is being being reproduced reliably by a well known NFS benchmark, but this gives more a bit more information on where a race condition in the inode lookup may exist. That is, the only common element here in these two lookup paths is that they are the only two calls to xfs_iget() with XFS_IGET_UNTRUSTED set in the flags. I doubt this is a coincidence.
