I would suggest to do it as suggested by PeterZ. Instead of set_bit(), however, it is probably better to use atomic_long_or() like
atomic_long_or_relaxed(RT_MUTEX_HAS_WAITERS, (atomic_long_t *)&lock->owner)
That function doesn't exist, atomic_long_or() is implicitly relaxed for not returning a value.
