Hi all,

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

error[E0308]: mismatched types
--> rust/kernel/lib.rs:204:9
|
204 | ptr.sub(offset) as *const $type
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ types differ in mutability

::: rust/kernel/workqueue.rs:495:18

495 | ) -> *mut Self {
| --------- expected `*mut ClosureWork<T>` because of return type
...
505 | / impl_has_work! {
506 | | impl{T} HasWork<Self> for ClosureWork<T> { self.work }
507 | | }
| |_- in this macro invocation
|
= note: expected raw pointer `*mut ClosureWork<T>`
found raw pointer `*const ClosureWork<T>`
= note: this error originates in the macro `$crate::container_of` which comes from the expansion of the macro `impl_has_work` (in Nightly builds, run with -Z macro-backtrace for more info)

error: aborting due to 1 previous error

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

Caused by commit

345e029b561e ("rust: workqueue: remove HasWork::OFFSET")

I have used the workqueues tree from next-20250414 for today.
