Subject: [031/117] ocfs2: Update VFS inodes id info after reflink.

2.6.33-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Tao Ma <tao.ma@...cle.com>

commit c21a534e2f24968cf74976a4e721ac194db30ded upstream.

In reflink we update the id info on the disk but forgot to update
the corresponding information in the VFS inode.  Update them
accordingly when we want to preserve the attributes.
