Since KVM now sanely handles debugfs init/destroy w.r.t. the VM, it is safe to hoist kvm_create_vm_debugfs() back into kvm_create_vm(). The author of this commit remains bitter for having been burned by the old wreck in commit a44a4cc1c969 ("KVM: Don't create VM debugfs files outside of the VM directory").
