    Subject[PATCH AUTOSEL 4.4 47/47] fuse: Add missed unlock_page() to fuse_readpages_fill()
    Date
    From: Kirill Tkhai <ktkhai@virtuozzo.com>

    [ Upstream commit 109728ccc5933151c68d1106e4065478a487a323 ]

    The above error path returns with page unlocked, so this place seems also
    to behave the same.

    Fixes: f8dbdf81821b ("fuse: rework fuse_readpages()")
