The API change is completed by the following commit: commit 63ef26930fe613a266cc69f5089cf643dd59b012 Author: Mathieu Desnoyers <[email protected]> Date: Sun Nov 13 14:07:57 2011 -0500 Tracepoint API change: combine TP_PROTO and TP_VARS into TP_ARGS, remove _NOARGS macros New API for tracepoints, combining the TP_PROTO and TP_VARS arguments into a single "TP_ARGS" macro. It takes up to 10 parameters (from 0 to 10). The "_NOARGS" special-case is not needed anymore: it can be achieved simply by passing an empty TP_ARGS: TP_ARGS(), to the standard tracepoint event declarations.
