Thanx clarifying.
I think I should read the notes in the first description (0/9) before
posting.
It says UUID is just for userspace.

Reading all 9 patches, I noticed handle_to_path() calls
exportfs_decode_fh() inconditionally.
Since exportfs_decode_fh() calls s_export_op->fh_to_dentry()
inconditionally too, handle_to_path() will crash when the target FS
doesn't support NFS-exporting, won't it?
