I don't think those questions need to be answered before proceeding
with this patchset. They're interesting questions, to be sure, but
to a large extent they're orthogonal to the changes here. I look
forward to continuing to work on those problems while filesystems
and the VFS continue to be converted to use folios.

Thank you. I appreciate that.
