REVIEWER'S NOTES
================

I am basing this on the mm-new branch in Andrew's tree, so let me know if I
should rebase anything here. Given the mm bits touched I did think perhaps
we should take it through the mm tree, however it may be more sensible to
take it through an fs tree - let me know!

Apologies for the noise/churn, but there are some prerequisite steps here
that inform an ordering - "fs: consistently use file_has_valid_mmap_hooks()
helper" being especially critical, and so I put the bulk of the work in the
same series.

Let me know if there's anything I can do to make life easier here.

Documentation/filesystems/porting.rst?

Also, an entry for ->mmap_prepare in Documentation/filesystems/vfs.rst
would be good.

I went there first to understand what the requirements of mmap_prepare
are, but there is nothing.

Ack, on it.
