From: Swapnil Pimpale Date: Tue, 5 Apr 2016 01:36:54 +0000 (-0400) Subject: staging: lustre: lov: Get the correct address of lmm_objects X-Git-Tag: v4.7-rc1~90^2~391 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=98b29828b71b19963f3b818bdbc3e8b32ffaa761;p=karo-tx-linux.git staging: lustre: lov: Get the correct address of lmm_objects 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.
