Subject: [PATCH v3 0/6] mm, swap: clean up swap cache mapping helper

From: Kairui Song <kasong@...cent.com>

This series removes usage of folio_index usage in fs/, and remove swap
cache checking in folio_contains.

Currently, the swap cache is already no longer directly exposed to fs,
and swap cache will be more different from page cache. Clean up the
helpers first to simplify the code and eliminate the helpers used for
resolving circular header dependency issue between filemap and swap
headers, and prepare for further changes.
