And looks there is now a fix for it:
https://lore.kernel.org/stable/CAOssrKez1mnF4rWRvWgk4LJ2iDfX8xkpMKvgprFt+-ARs83=nA@mail.gmail.com/
If you in meanwhile were able to reproduce it and can test the patch
as well that would be great.
712a951025c0 ("fuse: fix page stealing") in any case was backported as
well to 5.10.80, so would need to make sure that we do not release in
next point release a version newly affected.
