From: John L. Hammond <john.hamm...@intel.com> Use obd_get_info() to get the default and maximum LOV EA sizes (along with maximum cookiesize) from LOV. Remove the then unused function obd_size_diskmd() and the unused get info key KEY_LOVDESC. When computing the maximum LOV EA size use the active OST count (ld_active_tgt_count) rather than the OST count (ld_tgt_count).
