      KVM: use the correct RCU API for PROVE_RCU=y · 90d83dc3
      Lai Jiangshan 提交于
      The RCU/SRCU API have already changed for proving RCU usage.
      
      I got the following dmesg when PROVE_RCU=y because we used incorrect API.
      This patch coverts rcu_deference() to srcu_dereference() or family API.
      
      ===================================================
      [ INFO: suspicious rcu_dereference_check() usage. ]
      ---------------------------------------------------
      arch/x86/kvm/mmu.c:3020 invoked rcu_dereference_check() without protection!
      
      other info that might help us debug this:
