The change looks correct in principle. It would be good to automate looking
for other instances of this bug. How did you find it? Do you have e.g. a
coccinelle script or did you just stumble over the issue by accident?
Hi,
You can have an idea of the strategy used in this post:

Julia is currently working on a more complete strategy in order to find
such issues.
In the meantime, if you want, I can send the coccinelle scripts used.
Best regards,
CJ
