      block: Fix list corruption of blk stats callback list · 3f19cd23
      Jan Kara authored
      When CFQ calls wbt_disable_default(), it will call
      blk_stat_remove_callback() to stop gathering IO statistics for the
      purposes of writeback throttling. Later, when request_queue is
      unregistered, wbt_exit() will call blk_stat_remove_callback() again
      which will try to delete callback from the list again and possibly cause
      list corruption.
      
      Fix the problem by making wbt_disable_default() called wbt_exit() which
      is properly guarded against being called multiple times.
