    [PATCH] generic tag update · f39fc866
    Jens Axboe authored
    The following comes from James Bottemley, as he updated the SCSI layer
    to use the generic tagging.
    
    Basically just put blk_queue_tag_request() into ll_rw_blk.c and name it
    something more sane, blk_queue_find_tag(). In addition, remove REQ_CMD
    requirement in blk_queue_start_tag() -- this is actually IDE specific
    (we can only tag read/write requests there...), SCSI actually requires
    everything to be tagged once enabled. It's replaced with a safety check
    for an already tagged request.
