Thanks for the response. I think if it tears down the rport immediately and always calls back to the LLD it solves the problem.

Ahh. I understand. The wait_for_completions are in the lldd and I know
older code shows had the sequence you describe. True, if we reuse the
remoteport struct, as references never expired, the delete call would
have never occurred. So this is a bug with what's there.
I think the cleanest fix is to have the delete callback occur as soon as
the delete_associations are done - as that will always occur and do so
rather quickly. If needed, if we find we are reusing a remoteport struct
and we hadn't called the delete, we call it prior to returning to the
second register remoteport call, which should work as well.
note: as when we call remoteport_delete (ref cnt and free vs association
terminate) is independent from dev_loss_tmo, it shouldn't affect this
dev_loss patch set.
