I'm not sure a patch that is merely renaming a function should ever
have a Fixes tag, since it's just a naming issue, it doesn't fix a
bug, change functionality or anything like that.

I would suggest that there would need to be good reason why such a
patch should be backported to stable kernels - for example, something
else that does fix a user visible bug requires this change.

Thanks.
