38 * LL_* - works on the currently opened filehandle instead of parent dir
39 * *_OBD_* - gets data for both OSC or MDC (LOV, LMV indirectly)
40 * *_MDC_* - gets/sets data related to MDC
41 * *_LOV_* - gets/sets data related to OSC/LOV
42 * *FILE* - called on parent dir and passes in a filename
43 * *STRIPE* - set/get lov_user_md
44 * *INFO - set/get lov_user_mds_data
