Notes

Author	Note
	Priority reason: Requires write access to debugfs entries, which are restricted to root by default on Ubuntu kernels.
sbeattie	proposed patch references as fixing 40ce72b1951c (“Bluetooth: Move common debugfs file creation …”) but it looks like the race condition existed since the introduction of the conn_info_{min,max}_age_set() functions.
