    Subject[PATCH 5.4 061/348] fuse: ignore PG_workingset after stealing
    Date
    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."

    Reported-by: Thomas Lindroth <thomas.lindroth@gmail.com>
    Fixes: 1899ad18c607 ("mm: workingset: tell cache transitions from workingset thrashing")
