Subject: Re: [RFC PATCH v2 00/13] module: core code clean up

Hi Aaron,

  My apologies for not replying earlier.

  Thank you so much for doing this. I had a very similar approach, to
move code out based on the
  flags. I will am in the process of reviewing and testing the changes
you have posted.

Thanks.
