    Subject[PATCH 3.18 44/56] fuse: Add missed unlock_page() to fuse_readpages_fill()
    Date
    3.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Kirill Tkhai <ktkhai@virtuozzo.com>

    commit 109728ccc5933151c68d1106e4065478a487a323 upstream.

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

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