- * If we use both `packed` and `align(4)` for a struct, bindgen will generate
- * it as an opaque struct.
- *
- * `cras_server_state` is created from C with `packed` and `aligned(4)` and
- * shared through a shared memory area.
- *
- * Structs with `packed` and `align(4)` have the same memory layout as those
- * with `packed` except for some extra alignment bytes at the end.
- *
- * Therefore, using only `packed` for `cras_server_state` from Rust side is safe.
- *
- * This function modifies `cras_server_state` from
- * `__attribute__ ((packed, aligned(4)))` to `__attribute__ ((packed))`
