There's also Neil Brown's "wiggle" program for applying patches that don't apply.

https://github.com/neilbrown/wiggle

although on debian based systems I think you can just "apt install wiggle"

What does "applying patches that don't apply" mean exactly?

I know about wiggle, but I have not used it, to be honest.

It means that if you do "patch -p1 --dry-run < some.patch", and it complains that it doesn't apply, wiggle can sometimes apply it anyway, and also, if you do "patch -p1 < some.patch", and it partially applies but with rejected hunks, wiggle can try to apply the rejected hunks.
