Subject: [PATCH 00/17] nilfs2: Folio conversions for directory paths
Date: Mon, 27 Nov 2023 23:30:19 +0900 [thread overview]
Message-ID: <20231127143036.2425-1-konishi.ryusuke@gmail.com> (raw)
Hi Andrew,
please add this series to your queue for the next merge window.
This series applies page->folio conversions to nilfs2 directory
operations. This reduces hidden compound_head() calls and also
converts deprecated kmap calls to kmap_local in the directory code.
Although nilfs2 does not yet support large folios, Matthew has done
his best here to include support for large folios, which will be
needed for devices with large block sizes.
This series corresponds to the second half of the original post [1],
but with two complementary patches inserted at the beginning and some
adjustments, to prevent a kmap_local constraint violation found during
testing with highmem mapping.
[1] https://lkml.kernel.org/r/20231106173903.1734114-1-willy@infradead.org
I have reviewed all changes and tested this for regular and small
block sizes, both on machines with and without highmem mapping. No
issues found.
Thanks,
Ryusuke Konishi
