 4 *
 5 * Bindgen currently pretends that `enum lru_status` is the same as an integer.
 6 * This assumption is fine ABI-wise, but once you add CFI to the mix, it
 7 * triggers a CFI violation because `enum lru_status` gets a different CFI tag.
 8 *
 9 * This file contains a workaround until bindgen can be fixed.
