Why do you return noUpdate here? Shouldn't it return patchStatus instead?
| The trick is to cache the resource from the response of our update in an additional cache on top of the informer's cache. | ||
| If we read the resource, we first check if it is in the overlay cache and read it from there if present, otherwise read it from the cache of the informer. | ||
| If the informer receives an event with a fresh resource, we always remove the resource from the overlay | ||
| cache, since that is a more recent resource. But this **works only** if the update is done **with optimistic locking**. |

What does "update" refer to here? This isn't clear.
