The inverted atomic flag replaces test_and_set+clear with test_and_clear+set, essentially inverting the flag status. This makes more logical sense for flagging dirty state, which is less confusing than flagging clean state. The one caveat is ATOMIC_FLAG_INIT (or default construction in C++20) initializes the state to true rather than false.
