Subject: [PATCH 2/8] consistently use the LOCK an UNLOCK macros
In some places there has been a direct usage of the functions. Use the
macros consistently everywhere, such that it might be easier later on to
capture the fast path directly inside the macro and only have the call
overhead on the slow path.
