Subject: Re: [PATCH V2 5/9] MdeModulePkg/Variable: Add a file for NV variable functions
Date: Thu, 3 Oct 2019 18:43:15 +0000	[thread overview]
Message-ID: <DM6PR11MB3834E745EF278D57A5C0E9EBB59F0@DM6PR11MB3834.namprd11.prod.outlook.com> (raw)
In-Reply-To: <B80AF82E9BFB8E4FBD8C89DA810C6A093C940D5B@SHSMSX104.ccr.corp.intel.com>

I was debating on keeping this file in the patch series. I don't see a problem moving
those other functions. The goal was to break out some of the NV-specific content
from many of the other more generic functions in Variable.c Since you mentioned it,
I will make that change in V3, unless I hear back otherwise.

Thanks,
Michael
