ceph: use __page_cache_alloc and add_to_page_cache_lru
Following Nick Piggin patches in btrfs, pagecache pages should be allocated with __page_cache_alloc, so they obey pagecache memory policies. Also, using add_to_page_cache_lru instead of using a private pagevec where applicable. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
