The patch titled
Subject: mm: remove pagevec_lookup_entries
has been removed from the -mm tree. Its filename was
mm-remove-pagevec_lookup_entries.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
Subject: mm: remove pagevec_lookup_entries
pagevec_lookup_entries() is now just a wrapper around find_get_entries()
so remove it and convert all its callers.
