Is the reason that rport b's terminate_rport_io has not been called,

Oh wait, I think you also need to change the fc class to use
alloc_workqueue instead of create_singlethread_workqueue.

This seem to work, except that I had to use allow_workqueue with flags WQ_UNBOUND and max_active set to WQ_UNBOUND_MAX_ACTIVE. It didn't help With flags 0 and max_active set to 0. Test has been going on for the last 4 hours. I'll let it run overnight.

Thanks,
