Following debugfs object functions are not referenced within the code: int debugfs_valid_entry(const char *path); int debugfs_umount(void); int debugfs_write(const char *entry, const char *value); int debugfs_read(const char *entry, char *buffer, size_t size); void debugfs_force_cleanup(void); int debugfs_make_path(const char *element, char *buffer, int size); Removing them.

We don't need to have two PATH_MAX char sized arrays holding it, just one in util/debugfs.c will do. Also rename debugfs_path to tracing_events_path, as it is not the path to debugfs, that is debugfs_mountpoint. Both are now accessible. This will allow accessing this code in the perf python binding without having to drag in perf.c and util/parse-events.c. The defaults for these variables are the canonical "/sys/kernel/debug" and "/sys/kernel/debug/tracing/events/", removing the need for simple tools to call debugfs_mount(NULL).

No need for multiple definitions for STR() and die(), also use SuSv2's PATH_MAX instead of adding MAX_PATH.
