From d55800a4f2f34652c9e29f231511dc9b079db43e Mon Sep 17 00:00:00 2001
From: Scott Taylor <wonderboymusic@git.wordpress.org>
Date: Fri, 29 May 2015 17:03:13 +0000
Subject: [PATCH] In the style of #30947 and `default-filters.php`, add 2 new
 files to `wp-admin/includes`: `admin-filters.php` `ms-admin-filters.php`

There are random actions and filters littered among files like `misc.php`. These files contain functions that won't work outside of admin context and are typically only loaded in files that have already loaded the admin bootstrap.

See #32529.
