Citation needed.  All I see is Johannes' patch followed by your FUD.

Others have tested it already.

I'm not seeing it.

Those are only the ones not assigned to a specific person.  Yet, each
of them has a member of your team CC'ed.  Also, I made no effort to

ieee80211_notify_mac is creating locking problems.  I'd rather hit
a few disconnects than endure locking problems.

Now, if you could put as much energy into fixing these issues as you
