Excuse me, I do not quite understand your meaning. For me, if we are sure lv is always 4 for SO_TYPE, we don't need this patch. If lv may be 1 for SO_TYPE (it means val >> 8 may be zero), after call host_to_target_sock_type, val >> 8 may be non-zero, theoretically. In this case, we need modify lv to 4. >> For me, if you are sure, we can skip this patch. > > Does it fix something ? > It is only theoretical, not real world, at present.
