[v2,00/10] Convert ecryptfs to use folios

Message

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.

v2:
 - Switch from 'rc' to 'err' in ecryptfs_read_folio
 - Use folio_end_read() in ecryptfs_read_folio
 - Remove kernel-doc warnings that 0day warned about
 - R-b tags from Pankaj
