    block: remove plugging at buffered write time · 8430f977
    Fengguang Wu authored
    Buffered write(2) is not directly tied to IO, so it's not suitable to
    handle plug in generic_file_aio_write().
    
    Note that plugging for O_SYNC writes is also removed. The user may pass
    arbitrary @size arguments, which may be much larger than the preferable
    I/O size, or may cross extent/device boundaries. Let the lower layers
    handle the plugging. The plugging code here actually turns them into
    no-ops.
