Subject: [PATCH 00/12] nilfs2: Finish folio conversion

Andrew, please queue this series for the next cycle.

This series converts all remaining page structure references in nilfs2
to folio-based, except for nilfs_copy_buffer function, which was
converted to use folios in advance for cross-fs page flags cleanup.

This prioritizes folio conversion, and does not include buffer head
reference reduction, nor does it support for block sizes larger than
the system page size.

The first eight patches in this series mainly convert each of the
nilfs2-specific metadata implementations to use folios.  The last four
patches, by Matthew Wilcox, eliminate aops writepage callbacks and
convert the remaining page structure references to folio-based.  This
part reflects some corrections to the patch series posted by Matthew.

It has passed operation checks and load tests with different block
sizes on multiple environments, including 32-bit kernel, and is
sufficiently stable.

Thanks,
Ryusuke Konishi
