• • This is a function prologue which is used to allow calls to the current

• • kunit_activate_static_stub() to pass a replacement function in. The
• • replacement function will be called by KUNIT_TRIGGER_STATIC_STUB(), which

• • the function will continue execution as normal.
• • Example:
• • .. code-block:: c

• • int real_func(int n)
    

• • {
    

• •         KUNIT_STATIC_STUB_REDIRECT(real_func, n);
    

I wish there was a way to avoid having to repeat the function's name and arguments here...
