The rename makes sense, since the previous name was defined by a
specific use case rather than what it does. That said, it did imply a
lock context that makes the test result stable. Without that the
function could use a short comment, IMO. How about:

/* Test requires a stable page->memcg binding, see page_memcg() */

With that,
