The "list_limit" is set via module parameter so if you set that high
enough to lead to an integer overflow then you kind of deserve what
you get.
This patch is nice for kernel hardening and making the code easier to
read/audit but the real world security impact is negligible.
Agreed.
That is what I meant by "and unlikely".
Maybe the commit message could be more explicit if needed.
Let me know if ok as-is or if I should try to re-word the description.
