7Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
8Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
9becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
10
11It is important that the _PyThreadState_Current variable is always accessed
12with the same implementation of pyatomic.h. Use the PyThreadState_Get()
13function so extension modules will all reuse the same implementation.
