The patch titled
Subject: fs: cachefiles: use add_to_page_cache_lru()
has been removed from the -mm tree. Its filename was
fs-cachefiles-use-add_to_page_cache_lru.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: fs: cachefiles: use add_to_page_cache_lru()
This code used to have its own lru cache pagevec up until a0b8cab3
("mm: remove lru parameter from __pagevec_lru_add and remove parts of
pagevec API"). Now it's just add_to_page_cache() followed by
lru_cache_add(), might as well use add_to_page_cache_lru() directly.
