Ken:
I add my comment below. Besides, some modules in MdeModulePkg still
consumes VariableLock, such as UefiBootManagerLib, PcdDxe. Have you plan to
fix them also?

Use the correct directory name to pass Windows VS tool chain and Linux GCC
tool chain.

Liming,
I plan on fixing those modules as well. I created a new Bugzilla here: 3449
– VariablePolicy needs to replace VariableLock. (tianocore.org)
<https://bugzilla.tianocore.org/show_bug.cgi?id=3449>.
