Hi all,

After merging the rust tree, today's linux-next build (x86_64
allmodconfig) failed like this:

error[E0308]: mismatched types
--> drivers/gpu/drm/drm_panic_qr.rs:961:60
|
961 | let url_cstr: &CStr = unsafe { CStr::from_char_ptr(url) };
| ------------------- ^^^ expected `*const u8`, found `*const i8`
| |
| arguments to this function are incorrect
|
= note: expected raw pointer `*const u8`
found raw pointer `*const i8`
note: associated function defined here
--> rust/kernel/str.rs:187:19
|
187 | pub unsafe fn from_char_ptr<'a>(ptr: *const crate::ffi::c_char) -> &'a Self {
| ^^^^^^^^^^^^^

error: aborting due to 1 previous error

For more information about this error, try `rustc --explain E0308`.

Caused by commit

e721cd7570b2 ("rust: map `long` to `isize` and `char` to `u8`")

I have used the rust tree from next-20241213 for today.
