I just want to add that you are not limited to submitting a single batch of patches in a cycle. If you can get the first batch accepted in Xena, you are free to submit other batches in Xena. Just continue to bear in mind the date for freezing driver patches. The bottom line is the sooner you submit patches and work on resolving reviewer feedback, the sooner you can propose additional patches.

I concur with Brian.  I think doing a few at a time will be less likely
to overwhelm the review team and it will help to prevent repeated
comments in subsequent patches if you are able to proactively fix the
subsequent patches before they are submitted.

Thanks for seeking input on this!
