[PATCH RFC 10/11] KVM: nVMX: hyper-v: Hide more stuff under CONFIG_KVM_HYPERV

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



'hv_evmcs_vmptr'/'hv_evmcs_map'/'hv_evmcs' fields in 'struct nested_vmx'
should not be used when !CONFIG_KVM_HYPERV, hide them when
!CONFIG_KVM_HYPERV.

No functional change intended.
