[PATCH 06/12] KVM: MMU: rename kvm_mmu_reload

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

 



The name of kvm_mmu_reload is very confusing for two reasons:
first, KVM_REQ_MMU_RELOAD actually does not call it; second,
it only does anything if there is no valid root.

Rename it to kvm_mmu_ensure_valid_root, which matches the actual
behavior better.
