Context is no longer Sync so this doesn't work.
error[E0277]: `*mut ()` cannot be shared between threads safely
--> library/core/tests/task.rs:24:21

24 | static CONTEXT: Context<'static> = Context::from_waker(&WAKER);
| ^^^^^^^^^^^^^^^^ `*mut ()` cannot be shared between threads safely
|
= help: within `Context<'static>`, the trait `Sync` is not implemented for `*mut ()`
= note: required because it appears within the type `PhantomData<*mut ()>`
= note: required because it appears within the type `Context<'static>`
= note: shared static variables must have a type that implements `Sync`
