Sounds good! Thanks! Will hold for at least this week. Still need some more RBs.

Subject: [EXTERNAL] Re: [edk2-devel] [PATCH v7 00/14] Add the VariablePolicy feature
 
Hi Bret,

The V7 version is OK from my side.  Reviewed-by: Dandan Bi <dandan.bi@intel.com>
Please hold to see if any comments from other reviewers.


Hi Jiewen and Jian,

Do you have any comments?
 


Thanks,
Dandan

> Subject: [edk2-devel] [PATCH v7 00/14] Add the VariablePolicy feature
>
> The 14 patches in this series add the VariablePolicy feature to the core,
> deprecate Edk2VarLock (while adding a compatibility layer to reduce code
> churn), and integrate the VariablePolicy libraries and protocols into Variable
> Services.
>
> Since the integration requires multiple changes, including adding libraries, a
