--- Comment #6 from Paul Floyd <pjfloyd@wanadoo.fr> ---
If you can use a recent Valgrind (valgrind-devel or build from source) then
this should have been resolved.

Kyle Evans pointed out the same issue to me and I fixed it back in January
2024.

Here is the commit

https://sourceware.org/git/?p=valgrind.git;a=commit;h=d0c17b5431e5448c73f99322afb5aac442c2ee70

Other than painstakingly reading through the kernel source, is there any place
where information about ioctls is gathered together (something like
syscalls.master)?
