Merge patch series "Convert ecryptfs to use folios"

Matthew Wilcox (Oracle) <[email protected]> says:

The next step in the folio project is to remove page->index.  This
patchset does that for ecryptfs.  As an unloved filesystem, I haven't
made any effort to support large folios; this is just "keep it working".
I have only compile tested this, but since it's a straightforward
conversion I'm not expecting any problems beyond my fat fingers.
