 *       improved (and asymptotically superior) performance.

  With this patch, the external provisioner can remove the finalizer in next reconcile loop. Unfortunately if the provious existing pv has the Failed state, this patch won't take effort. It requires users to remove finalizer. ([#126045](https://github.com/kubernetes/kubernetes/pull/126045), [@carlory](https://github.com/carlory)) [SIG Apps and Storage]
