Please apply this series to the 6.1-stable tree.
This series makes it possible to backport the latter two patches (fixing some syzbot issues and a use-after-free issue) that could not be backported to 6.1.y.
To achieve this, one dependent patch (patch 1/3) is included, and each patch is tailored to avoid extensive page/folio conversion. Both adjustments are specific to nilfs2 and do not include tree-wide changes.
It has also been tested against the latest 6.1.y.
Thanks, Ryusuke Konishi
