fs: drop_caches: draining pages before dropping caches
We expect a file page access after dropping caches should be a major
fault, but sometimes it's still a minor fault. That's because a file page
can't be dropped if it's in a per-cpu pagevec. Draining all pages from
per-cpu pagevec to lru list before trying to drop caches.
