[PATCH 3/6] Bluetooth: Add skeleton for self-test module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johan Hedberg <johan.hedberg@xxxxxxxxx>

This patch adds a basic skeleton for a new self-test module. The module
will be used to implement various self-tests for the bluetooth
subsystem. The first user will be SMP, for which it is of particular
importance that this is as a separate module to avoid loading priority
conflicts with the crypto subsystem and the rest of the Bluetooth
subsystem.
