3/* C helper for page_range.rs to work around a CFI violation.
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.
