Subject: [patch 1/9] fs: cachefiles: use add_to_page_cache_lru()
Date: Mon, 2 Dec 2013 14:21:40 -0500 [thread overview]
Message-ID: <1386012108-21006-2-git-send-email-hannes@cmpxchg.org> (raw)
In-Reply-To: <1386012108-21006-1-git-send-email-hannes@cmpxchg.org>
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.
