230 * dirty hack, we set LDLM_FL_LVB_READY only after we've done the LVB poop.
231 * this is only needed on LOV/OSC now, where LVB is actually used and
232 * callers must set it in input flags.
234 * The proper fix is to do the granting inside of the completion AST,
235 * which can be replaced with a LVB-aware wrapping function for OSC locks.
