Subject[PATCH 09/18] staging: lustre: lov: Get the correct address of lmm_objects
Date
From: Swapnil Pimpale <spimpale@ddn.com>

The introduction of lmm_layout_gen makes the assumption that
lmm_objects is present after lmm_stripe_count incorrect.
Fixed this to get the correct address of lmm_objects when lmmk is cast
to lov_mds_md_v1.
