If we don't care about blktrace for passthrough io after del_gendisk(),

QUEUE_FLAG_REGISTERED in blk_trace_setup(), and don't enable blktrace
in the first place.

Any suggestions about this problem? Should we use separate handling for
/dev/sd? Or just free blktrace in blk_free_queue().

I'd be fine with trying to either remove the /dev/sg blktrace handling
and / or splitting it up so that it doesn't interact with the main disk
based one.  I can look into this if you want, or leave it to you.


Ok, I'll send a v2 to free blktrace in disk_release(), in the meantime
I'll take a look how to handle blktrace for /dev/sg.

Thanks,
Kuai
