Hi Everyone, Due to lack of information, I think I'll go ahead and pick up a simple solution for this(i.e. the code I attached previously to set a flag event_driven in scsi_device to let sr skip events poll) and send a new series out for you to review. After all, I can't wait forever... Please feel free to let me know if you don't think I should send a new series with the above mentioned solution. Thanks a lot for your(all of you) kind help and comments. -Aaron On 12/11/2012 01:10 PM, Tejun Heo wrote: > Hello, guys. > > On Mon, Dec 10, 2012 at 11:26:07AM +0800, Aaron Lu wrote: >>>>> The problem here is there's no easy to reach genhd from libata (or the >>>>> other way around) without going through sr.
