The argument @direct is vcpu->arch.mmu->root_role.direct, so just use

It's worth calling out that, unlike non-root page tables, it's impossible to have
a direct root in an indirect MMU. I.e. provide a hint as to why there's a need to
pass @direct in the first place.
I suppose there's *no* need to pass direct? Also, there's the trivial
(but less interesting) justification that kvm_mmu_load does
if (vcpu->arch.mmu->root_role.direct)
r = mmu_alloc_direct_roots(vcpu);
else
r = mmu_alloc_shadow_roots(vcpu);
and those are the only callers of mmu_alloc_root.
