[PATCH] KVM: nVMX: fix comments of handle_vmon()

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

 



"VMXON pointer" is saved in vmx->nested.vmxon_ptr since
commit 3573e22cfeca ("KVM: nVMX: additional checks on
vmxon region"). Also, handle_vmptrld() & handle_vmclear()
now have logic to check the VMCS pointer against the VMXON
pointer.

So just remove the obsolete comments of handle_vmon().
