[PATCH] KVM: VMX: Rename vmx_get_max_tdp_level to vmx_get_max_ept_level
Posted by Shiyuan Gao 2 years, 1 month ago
In vmx, ept_level looks better than tdp level and is consistent with
svm get_npt_level().

Anyone else have an opinion on this?  I'm leaning toward applying it, but a small

that part of me gets even smaller...).
