3.4-rt which lacks two RT features from 3.6: SLUB support and the split softirq lock implementation. SLUB has a way better performance than SLAB on RT and the split softirq lock implementation is necessary especially for realtime networking applications. The following patch series backports these features to 3.4-rt. Steven, could you please apply these patches to a separate 3.4-rt-features branch?
