[PATCH 00/20] nilfs2: Folio conversions for file paths

[Ryusuke Konishi]

Hi Andrew, please queue this series for the next merge window.

This series advances page->folio conversions for a wide range of
nilfs2, including its file operations, block routines, and the log
writer's writeback routines.  It doesn't cover large folios support,
but it saves a lot of hidden compound_head() calls while preserving
the existing support range behavior.

The original series in post [1] also covered directory-related
page->folio conversions, but that was put on hold because a regression
was found in testing, so this is an excerpt from the first half of the
original post.

[1] https://lkml.kernel.org/r/20231106173903.1734114-1-willy@xxxxxxxxxxxxx

I tested this series in both 32-bit and 64-bit environments, switching
between normal and small block sizes.  I also reviewed all changes in
all patches to ensure they do not break existing behavior.

There were no problems, so I'm sending this part first because I would
like you to keep it in the -mm tree at an early stage.

Thanks,
Ryusuke Konishi
