    * `tf.types.experimental.TraceType` now allows custom tf.function inputs to declare Tensor decomposition and type casting support.

  ### Issue
  Fixes #135757 ([#135759](https://github.com/kubernetes/kubernetes/pull/135759), [@Abhigyan-Shekhar](https://github.com/Abhigyan-Shekhar)) [SIG API Machinery and CLI]

type Mutex struct         { /* Mutex fields */ }
func (m *Mutex) Lock()    { /* Lock implementation */ }
func (m *Mutex) Unlock()  { /* Unlock implementation */ }

// NewMutex has the same composition as Mutex but its method set is empty.
type NewMutex Mutex

// The method set of PtrMutex's underlying type *Mutex remains unchanged,
// but the method set of PtrMutex is empty.
type PtrMutex *Mutex
