I'm confused as to where the class->stat objects are initialised? Is that done in lock_stat_init()? If so, then you have a bug.
static struct lock_class lock_classes[MAX_LOCKDEP_KEYS]; I assume this gets us class structures containing all zeros, doesn't it? Then class->stat is zeros as well, which is handled by lib/statistics. (In this case, data gathering hasn't been turned on yet, and statistic_inc() and similar functions don't access other areas of struct statistic.)
