[CentOS] xfs, inode64, and NFS

we recently deployed some large XFS file systems with centos 6.2 used as 
NFS servers...

I've had some reports of a problem similar to the one reported here...
http://www.linuxquestions.org/questions/red-hat-31/xfs-inode64-nfs-export-no_subtree_check-and-stale-nfs-file-handle-message-855844/

these reports are somewhat vague (third indirectly reported via internal 
corporate channels from sites in the far east).

is anyone familiar with this inode64 stuff and NFS in EL6.2 ?
