Thanks for the report. As Thorsten noted, Arpith already posted a fix
at:
https://lore.kernel.org/all/20260310102233.391113-1-arpithk@nvidia.com/
with Al Viro's review feedback still pending. There is no upstream
commit to cherry-pick yet, so I cannot queue anything for stable until
an upstream fix lands.

Thanks,
