Hi, This is the 3rd version of the raw tracepoint events on modules. The previous version is here;
https://lore.kernel.org/all/fbfec8d9-d0ed-4384-bbd2-dd5c1e568...@efficios.com/ This version supports tracepoint event on unloaded modules according to Mathies' suggestion ([2/5],[4/5] and part of [5/5]) . The concern about blocking module unload by instrumentation is TBD. Note, to support tracepoints in the unloaded modules, tracepoint event can not check the given tracepoint is really defined or not. So unless CONFIG_MODULES=n, it does not check the tracepoint existence. IOW, user can specify any tracepoint name for tracepoint events. It will be just ignored.
