That said, it sure is simpler to implement, so I'm all for it!

hmm, not sure why it is simpler.

When you ask the question, "which container owns this page?", you don't

have to look far,

as in page->mapping->container for user land?

in case of anon_vma, page->mapping can be the same
for 2 pages beloning to different containers.

nor is it ambiguous in any way.  It is very strict,
and very straightforward.

What additional ambiguity you have when inode or task structures have
the required information.

inodes can belong to multiple containers and so do the pages.
