The choice of a kernel-tracepoint approach had advantages since it places no inherent limitation on maximum number of arguments that can be logged. Also, it is flexible enough to dump entire arrays if need be -- which is not as easily accomplished in the proposed approach as with kernel tracepoints. -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India
