From: Miklos Szeredi <mszeredi@redhat.com>
commit b89ecd60d38ec042d63bdb376c722a16f92bcb88 upstream.
Fix the "fuse: trying to steal weird page" warning.
Description from Johannes Weiner:
"Think of it as similar to PG_active. It's just another usage/heat indicator of file and anon pages on the reclaim LRU that, unlike PG_active, persists across deactivation and even reclaim (we store it in the page cache / swapper cache tree until the page refaults).
So if fuse accepts pages that can legally have PG_active set, PG_workingset is fine too."
