I think this is also what I wrote a long time. And also this sysfs hack should not go to upstream.
Over the years there has been some talk about solving the BT coex properly, but I haven't seen any patches. I guess the proper solution would be that BT subsystem in kernel would notify wireless drivers about BT use?
