    Description

      It looks like lustre_swab_fiemap can go beyond request buffer as it uses extent count number from network without any checking at face value

      similar problem exist at lustre_swab_lmv_mds_md_v1 for lmm1->lmv_stripe_count

      lustre_swab_object_update for ou->ou_params_count
