| * VMStateStructMember: Metadata about a single member of the struct |

| * members of the struct aside from the main struct member that's |
| * being migrated. |
| * |
| * One situation where extra fields are referenced is the common case |
| * of a struct containing an array or buffer, the size of which is |
| * stored in another member of the same struct. |
| * |
| * Example 1: |
| * struct IDEState { |

| * uint8_t *io_buffer; |
| * int32_t io_buffer_total_len; |
| * ... |
| * } |
| * VMSTATE_VARRAY_INT32(io_buffer, IDEState, io_buffer_total_len, 1, |
| * vmstate_info_uint8, uint8_t) |
| * |
| * In the above, io_buffer is the main field being migrated by the |
| * VMSTATE_VARRAY while io_buffer_total_len is the meta field that |
| * provides the size of the io_buffer. In this particular case, |
| * io_buffer_total_len is never migrated. |
| * |
| * Example 2: |
| * struct SpaprMachineState { |
| * ... |
| * uint32_t fdt_size; |
| * void *fdt_blob; |
| * ... |
| * } |
| * VMSTATE_UINT32(fdt_size, SpaprMachineState), |
| * VMSTATE_VBUFFER_ALLOC_UINT32(fdt_blob, SpaprMachineState, 0, NULL, fdt_size), |
| * |
| * Here, fdt_blob is the field being migrated by VMSTATE_VBUFFER_ALLOC |
| * and fdt_size is the meta field providing the size. In this case, |
| * the extra field is also independently migrated by the |
| * VMSTATE_UINT32 above. |
