    locking/rwsem: Get rid of __down_write_nested() · f8e04d85
    Michal Hocko authored
    This is no longer used anywhere and all callers (__down_write()) use
    0 as a subclass. Ditch __down_write_nested() to make the code easier
    to follow.
    
    This shouldn't introduce any functional change.
