This is a patchset designed to make key setup slightly clearer to me
ahead of rearranging it to add extent-based encryption. It is basically
a subset of my prior changeset [1] for elegance. The subsequent changes
have minor dependencies on it; I can drop this changeset if it's
preferable, although I do think it makes everything cleaner.

Patchset is built on kdave/misc-next as per base commit and needs a tiny
fixup to apply to fscrypt/for-next. It passes ext4/f2fs tests for me.
