[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.

Matthew Wilcox (Oracle) (10):
  ecryptfs: Convert ecryptfs_writepage() to ecryptfs_writepages()
  ecryptfs: Use a folio throughout ecryptfs_read_folio()
  ecryptfs: Convert ecryptfs_copy_up_encrypted_with_header() to take a
    folio
  ecryptfs: Convert ecryptfs_read_lower_page_segment() to take a folio
  ecryptfs: Convert ecryptfs_write() to use a folio
  ecryptfs: Convert ecryptfs_write_lower_page_segment() to take a folio
  ecryptfs: Convert ecryptfs_encrypt_page() to take a folio
  ecryptfs: Convert ecryptfs_decrypt_page() to take a folio
  ecryptfs: Convert lower_offset_for_page() to take a folio
  ecryptfs: Pass the folio index to crypt_extent()
