Subject: LU-3162 lov: Get the correct address of lmm_objects
X-Git-Tag: 2.4.91~20
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=b3edbd0f5f9ef10941b98f2b82606916b850374a;hp=0a56d6db644b4009519429ba1b1463c7dd788167

LU-3162 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.
