Subject: nilfs2: add nilfs_end_folio_io()
Date: Tue, 14 Nov 2023 17:44:17 +0900
Patch series "nilfs2: Folio conversions for file paths".
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.
This patch (of 20):
This is the folio counterpart of the existing nilfs_end_page_io() which is
retained as a wrapper of nilfs_end_folio_io(). Replaces nine hidden calls
to compound_head() with one.
