From 2fd6f55c048d0c863ffbc8590b1bd2edb5ff13e5 Mon Sep 17 00:00:00 2001 From: Gary Guo Date: Fri, 13 Sep 2024 22:29:22 +0100 Subject: rust: map `__kernel_size_t` and friends also to usize/isize Currently bindgen has special logic to recognise `size_t` and `ssize_t` and map them to Rust `usize` and `isize`. Similarly, `ptrdiff_t` is mapped to `isize`. However this falls short for `__kernel_size_t`, `__kernel_ssize_t` and `__kernel_ptrdiff_t`. To ensure that they are mapped to usize/isize rather than 32/64 integers depending on platform, blocklist them in bindgen parameters and manually provide their definition.
