Hey Ming,
Seems using a real nvme device at the target vs a ram device, avoids this new
deadlock issue. And I'm running so-far w/o the usual touch-after-free crash.
Usually I hit it quickly. It looks like your patch did indeed fix that. So:
1) We need to address Christoph's concern that your fix isn't the ideal/correct
solution. How do you want to proceed on that angle? How can I help?
2) the deadlock below is probably some other issue. Looks more like a cxgb4
problem at first glance. I'll look into this one...
Steve.
