Re: [PATCH 1/2] Bluetooth: notify userspace of security level change

It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

What happens to in-flight data already written but not yet consumed?  I'm
smelling a possible race condition with data sent under the old level but
read under the new level....
