    locking/rwsem: Remove rwsem_atomic_add() and rwsem_atomic_update() · d157bd86
    Jason Low authored
    The rwsem-xadd count has been converted to an atomic variable and the
    rwsem code now directly uses atomic_long_add() and
    atomic_long_add_return(), so we can remove the arch implementations of
    rwsem_atomic_add() and rwsem_atomic_update().
