    bcache: New writeback PD controller · 16749c23

    The old writeback PD controller could get into states where it had throttled all
    the way down and take way too long to recover - it was too complicated to really
    understand what it was doing.
    
    This rewrites a good chunk of it to hopefully be simpler and make more sense,
    and it also pays more attention to units which should make the behaviour a bit
    easier to understand.
