I'm not telling you what to do -- I'm just asking.

But it does seem to me that the kernel knows better when to disconnect
a connection -- eg I don't think an error completion will be signaled
to userspace.  Conversely if a target goes away and comes back with no
IOs submitted in between, then the connection should survive and
there's no reason to disconnect/reconnect.
