Call update_post_parent_caches in the_post function in WP_Query class

[priyankkpatel]

Hello Team,

In the_post function class WP_Query, update_post_author_caches is already in use but not update_post_parent_caches.

I am not sure if it is because of update_post_parent_caches calls the private function _prime_post_caches or what.

@priyankkpatel Can you provide anymore context here? Why is it needed to prime the caches on post parents in the loop. A standard loop does not call the parent. There is nothing stopping you from call update_post_parent_caches within your own code, if you have an issue in your own theme/plugin.
