Hi all, After merging the tip tree, today's linux-next build (x86_64 allmodconfig) failed like this: error[E0594]: cannot assign to data in dereference of `lock::Guard<'_, T, MutexBackend>` --> rust/kernel/debugfs/traits.rs:64:9 | 64 | *self.lock() = val; | ^^^^^^^^^^^^ cannot assign | = help: trait `DerefMut` is required to modify through a dereference, but it is not implemented for `lock::Guard<'_, T, MutexBackend>` error: aborting due to 1 previous error For more information about this error, try `rustc --explain E0594`. Caused by commit da123f0ee40f ("rust: lock: guard: Add T: Unpin bound to DerefMut") I have used the tip tree from next-20251021 for today. -- Cheers, Stephen Rothwell
