      xfs: use a normal shrinker for the dquot freelist · 92b2e5b3
      Christoph Hellwig 提交于
      Stop reusing dquots from the freelist when allocating new ones directly, and
      implement a shrinker that actually follows the specifications for the
      interface.  The shrinker implementation is still highly suboptimal at this
      point, but we can gradually work on it.
      
      This also fixes an bug in the previous lock ordering, where we would take
      the hash and dqlist locks inside of the freelist lock against the normal
      lock ordering.  This is only solvable by introducing the dispose list,
      and thus not when using direct reclaim of unused dquots for new allocations.
      
      As a side-effect the quota upper bound and used to free ratio values in
      /proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the
      new world order.
