    Subject[PATCH 0/2] make kvm guest mode to be rcu quiescent state
    Date
    CPU may spend a lot of time in a guest mode while other CPUs wait for
    rcu grace period to elapse. This patch series makes guest mode into
    quiescent state to shorten wait time.

    Gleb Natapov (2):
    rcu: provide rcu_virt_note_context_switch() function.
    KVM: make guest mode entry to be rcu quiescent state
