<div dir="ltr">Hi Nic,<div> </div><div>Yes, i will split this into smaller patches and take care of the TODO's. I will have a v1 patch set ready with these changes within a couple of days. Given the 4/10 deadline for 22.07 it would seem that 22.11 is our target.</div><div> </div><div>Thank you,</div><div>-John</div><div> </div></div> <div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Apr 27, 2022 at 2:38 PM Chautru, Nicolas <<a href="mailto:nicolas.chautru@intel.com">nicolas.chautru@intel.com</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi John, Do you think this one can be split into a few incremental commits? There are a few TODOs, is that v1 ready for review? Also you are targeting 22.11 right?
