3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pekon Gupta <pekon@ti.com>
commit bb38eefb6858ce16b34716145b9597a5680aa54c upstream.
This patch excludes reserved-marker byte-position from oobfree->length calculation. Thus all bytes from oobfree->offset till end of OOB are free.
