Thanks, can I add your Reviewed-by on all three?

There's a problem with trans_fd read_work and cancelled callback; I'm
not so sure about refcount but we can definitely get double list_del
as we're not checking the status. I think when we incorrectly remove
from the list we also mismanage the refcount, but honestly need to
test..
