Hi, here is the backport of (hopefully) all workingset related fixes for 4.4 kernel. The series has been reviewed by Johannes [1]. The main motivation for the backport is 22f2ac51b6d6 ("mm: workingset: fix crash in shadow node shrinker caused by replace_page_cache_page()") which is a fix for a triggered BUG_ON. This is not sufficient because there are follow up fixes which were introduced later.
