The* bitfield size is set for bitfield members. If the type* info kind_flag is not set, the offset contains only bit* offset.)否则If the type info kind_flag is set, the btf_member offset* contains both member bitfield size and bit offset. The* bitfield size is set for bitfield members. If the type* info kind_flag is not set, the offset contains only bit* offset.
