Thanks for replying. I have not encountered any trouble in reality
world. Actually I just find that this code can't work well when I'm
search QUEUE_FLAG_ADD_RANDOM. I'm not familiar with ide world. Please
let me know if I miss something.

Also there are several device drivers still calling
'blk_queue_flag_clear(QUEUE_FLAG_ADD_RANDOM, q)', though they have
migrated to mq and have no need clearing QUEUE_FLAG_ADD_RANDOM.
