 The function definition of wp_cache_flush doesn't have a do_action call,
 and neither does WP_Object_Cache->flush.

 https://core.trac.wordpress.org/browser/tags/4.9.8/src/wp-
 includes/cache.php#L97
 https://core.trac.wordpress.org/browser/tags/4.9.8/src/wp-
 includes/cache.php#L498

 I want to be able to run additional code whenever the object cache is
 flushed but currently I can't.

 Fixing this should be as trivial as adding
 {{{
 do_action('wp_cache_flush');
 }}}

 to the function definition of wp_cache_flush.

 I don't care about the name of the action or if it runs before or after
 the flush, I'd just like to have this functionality in the core.
 Preferably before WordPress 6.0.
