Hey Ming,
For what its worth, the change you proposed in this thread isn't working for me.
I see maybe one or two recoveries successful, then the target gets stuck. I see
several workq threads stuck destroying various qps, one thread stuck draining a
qp. If this change is not the proper fix, then I'm not going to debug this
further.
