Were any source code analysis tools involved for finding these update candidates?

With the help of Coccinelle. You can find out some example in scripts/coccinelle/.

Thanks for such background information. Was the script “ifnullfree.cocci” applied here?

Yep

Will it be helpful to add attribution for such tools to any more descriptions in your patches?

Sometimes, I will add the description in my patches. Not always.

Thanks, zhong jiang
