Batch limiting was being experimented since 2.6.1 and throttling patch was published in July 2004. The throttling patch introduced the boot paramenter rcu.maxbatch which limits the maximum number of finished callbacks executed in one batch (default 10). IIRC, that was merged in Aug 2004. The 2.6.14 patch increased the default to 10000 and introduced forced reschedule based on queue length. The latest patch automatically swings between a batch limit of 10 and no limit at all when the system needs a kick in the rear end.
