I did a quick review, it looks mostly good, but as it's sensitive code i would like to spend sometime on it. Probably next week. Note that i had some work on this area too, i mostly want to drop all the debugfs related to this and add some new more usefull (basicly something that allow you to read all the data needed to replay a locking up ib). I also was looking into Dave reset thread and your solution of moving reset in ioctl return path sounds good too but i need to convince my self that it encompass all possible case. Cheers, Jerome
