Also fixed record->cpu to match the CPU that's also passed to the callback, instead of always being zero. - Loading of events with tracefs_local_events(), tracefs_local_event_system() and tracefs_fill_local_events() now pull in kallsyms, saved_cmdlines, and printk_format mappings into the tep handler. - New API to reload the saved_cmdlines tracefs_load_cmdlines() - Warnings now can be overwritten with tracefs_warning() and no longer the too generic name warning() - All files opened in the library now are done so with O_CLOEXEC - Cleaner building and installation. -- Steve
