-### What it does
-Check for empty spin loops
-
-### Why is this bad?
-The loop body should have something like `thread::park()` or at least
-`std::hint::spin_loop()` to avoid needlessly burning cycles and conserve
-energy. Perhaps even better use an actual lock, if possible.
-
-### Known problems
-This lint doesn't currently trigger on `while let` or
-`loop { match .. { .. } }` loops, which would be considered idiomatic in
-combination with e.g. `AtomicBool::compare_exchange_weak`.
-
-### Example
-
-```
-use core::sync::atomic::{AtomicBool, Ordering};
-let b = AtomicBool::new(true);
-// give a ref to `b` to another thread,wait for it to become false
-while b.load(Ordering::Acquire) {};
-```
-Use instead:
-```
-while b.load(Ordering::Acquire) {
-    std::hint::spin_loop()
-}
-```
