The ENOENT was coming from xfs_iget. (It's tempting to wonder whether we should just map all xfs_iget errors to ESTALE, but I don't believe so--xfs_iget can also return ENOMEM at least, which we wouldn't want mapped to ESTALE.) While we're at it, the other return of ENOENT in xfs_nfs_get_inode() also looks wrong. Signed-off-by: J.
