6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Miguel Ojeda <ojeda@xxxxxxxxxx> commit 5e7c9b84ad08cc7a41b2ddbbbaccb60057da3860 upstream. Rust 1.58.0 (before Rust was merged into the kernel) made Clippy's `non_send_fields_in_send_ty` lint part of the `suspicious` lint group for a brief window of time [1] until the minor version 1.58.1 got released a week after, where the lint was moved back to `nursery`. By that time, we had already upgraded to that Rust version, and thus we had `allow`ed the lint here for `CondVar`. Nowadays, Clippy's `non_send_fields_in_send_ty` would still trigger here if it were enabled. Moreover, if enabled, `Lock<T, B>` and `Task` would also require an `allow`. Therefore, it does not seem like someone is actually enabling it (in, e.g., a custom flags build). Finally, the lint does not appear to have had major improvements since then [2]. Thus remove the `allow` since it is unneeded.
