Subject: Re: [PATCH v3 1/1] mm: page_alloc: skip over regions of invalid pfns
 on UMA

Hello linux-mm community,

Everyone of you might have and probably do have more important tasks in
their queue, compared to the boot optimization discussed in this email
chain.

Still, this patch is important for our organization, our community and
our suppliers. So, I still hope that we will be able to move forward
with it somehow, especially because it has received positive feedback
from Matthew Wilcox and Pavel Tatashin. Michal Hocko suggested that a
previous version of this patch might be more appropriate due to its
simplicity and slightly better readability.

Many thanks for your participation so far.

Best regards,
Eugeniu.
