For several reasons, it would be beneficial to kill off ACCESS_ONCE() tree-wide, in favour of {READ,WRITE}_ONCE(). These work with aggregate types, more obviously document their intended behaviour, and are necessary for tools like KTSAN to work correctly (as otherwise reads and writes cannot be instrumented separately). While it's possible to script the bulk of this tree-wide conversion, some
