Subject: linux-next: build failure after merge of the modules tree
Date: Tue, 4 Nov 2025 15:45:00 +1100 [thread overview]
Message-ID: <20251104154500.5acb5340@canb.auug.org.au> (raw)

Hi all,
After merging the modules tree, today's linux-next build (x86_64
allmodconfig) failed like this:
error[E0308]: mismatched types
--> rust/kernel/module_param.rs:75:47
|
75 | let new_value = T::try_from_param_arg(arg)?;
| --------------------- ^^^ expected `&BStr`, found `&CStr`
| |
| arguments to this function are incorrect
|
= note: expected reference `&BStr`
found reference `&ffi::CStr`
note: associated function defined here
--> rust/kernel/module_param.rs:32:8
|
32 | fn try_from_param_arg(arg: &BStr) -> Result<Self>;
| ^^^^^^^^^^^^^^^^^^
error: aborting due to 1 previous error
For more information about this error, try `rustc --explain E0308`.
Caused by commit
0b08fc292842 ("rust: introduce module_param module")
This is some interaction with something later in linux-next - presumably
commit
3b83f5d5e78a ("rust: replace `CStr` with `core::ffi::CStr`")
from the rust tree.
Hopefully someone can provide a resolution for me tomorrow.
I have used the modules tree from next-20251103 for today.

Cheers,
