...evious time. Could you please Ack use of rcu_dereference/rcu_assign_pointer there? Eric Dumazet proposed that I open-code these, he suggested that this is an abuse of these macros and not enough like RCU. What is your opinion?

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
