Michael, do you have a quick way to check if srcu has a noticeable impact on int injection on your systems? I am happy with either v2 or v3 of the patch, but srcu_synchronize_expedited seems to have less latency impact on the full system than rcu_synchronize_expedited. This might give Paolo a hint which of the patches is the right way to go.
