The actual patch is fine I think. The discussion was about improving the explanation of exactly what's happening in the change log, and whether there is a larger bug causing FP corruption unrelated to io-uring. I'm now reasonably confident there's no detectable corruption of fr0 happening except via the io-uring -> clone path. It's still a bad bug for us to corrupt fr0 across sys_clone(), but in practice it doesn't affect userspace because fr0 is volatile across function calls. cheers
