The patch titled
Subject: mm: use page->deferred_list
has been removed from the -mm tree. Its filename was
mm-use-page-deferred_list.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Matthew Wilcox <mawilcox@xxxxxxxxxxxxx>
Subject: mm: use page->deferred_list
Now that we can represent the location of 'deferred_list' in C instead of
comments, make use of that ability.
