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.
Christian
