Looks OK, except for the little docstring nitpick below:

There's no way the code can check whether the value is "a predicate
function that checks if directory has changed on disk" (it's one of
those halting-problem-equivalent).
So really it should just say

   If its value is a function, call this function with the directory
   name as single argument and revert the buffer if it returns non-nil.
