    ide: clear ide_req()->special for non-passthrough requests · 9334ae5e
    Jens Axboe authored
    The initial patch cleared this for all requests, which is wrong
    since internal uses can't have this cleared as that's what they
    are using to pass data. The fix moved the initialization to the
    mq_ops->initialize_rq_fn(), but that's only a partial fix since
    it only catches uses from blk_get_request(), not requests coming
    from the file system.
    Keep the non-fs initialization, and add the IDE entry clear
    IFF RQF_DONTPREP isn't set and it's a passthrough request.
    Fixes: d16a6766 ("ide: don't clear special on ide_queue_rq() entry")
    Fixes: 22ce0a7c ("ide: don't use req->special")
