And looks there is now a fix for it: https://lore.kernel.org/stable/CAOssrKez1mnF4rWRvWgk4LJ2iDfX8xkpMKvgprFt+-ARs83=n...@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.
