To clarify, while this is technically true currently, as I mentioned it's been
kept flexible enough such that a filesystem *could* store the metadata elsewhere
with only some slight changes to the common fs/verity/ code which won't break
other filesystems. Though of course, keeping all filesystems using the
"metadata after EOF" approach does allow a couple simplifications.
