From c2adc15b450387fc30de6c59124ac7ce725b1fe4 Mon Sep 17 00:00:00 2001 From: Scott Taylor Date: Sun, 9 Feb 2014 21:47:12 +0000 Subject: [PATCH] Collect the post and link ids that will be reassigned before running the update in `remove_user_from_blog()`. Use `array_walk()` instead of `array_map()` when invalidating the caches for the collected ids. Props kovshenin. Fixes #25545.
