[PATCH 1/9] tracing: Convert module refcnt events to DEFINE_EVENT
|
|
Use TRACE_EVENT_TEMPLATE to remove duplicate code:
text data bss dec hex filename
29854 1980 128 31962 7cda kernel/module.o.old
28750 1980 128 30858 788a kernel/module.o
Two events are converted:
module_refcnt: module_get, module_put
