Description

A crash happens on

kernel: LustreError: 3330576:0:lod_object.c:7227:lod_declare_update_extents() ) ASSERTION( start_index == 0 && max_comp == lo->ldo_comp_cnt ) failed:                               
kernel: LustreError: 3330576:0:(lod_object.c:7227:lod_declare_update_extents()  ) LBUG

The lod::ldo_flr_state is only meaningful for composite layout, while a plain file could get into lod_declare_update_plain()->lod_declare_update_extents() and bump into this assertion.
