    [PATCH] end_io bouncing · d50059ec
    Jens Axboe authored
    o Split blk_queue_bounce() into a slow and fast path. The fast path is
      inlined, only if we actually need to check the bio for possible
      bounces (and bounce) do we enter __blk_queue_bounce() slow path.
    
    o Fix a nasty bug that could cause corruption for file systems not
      using PAGE_CACHE_SIZE blok size! We were not correctly setting the
      'to' bv_offset correctly.
    
    o Add BIO_BOUNCE flag. Later patches will use this for debug checking.
