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.
