I'm not sure why you changed the order of the patches.
Now, the second one is the fix, so it will make the backport more
difficult. Either both are considered to be fixes. I think it can make 
sense as the renaming does not introduce risk of regression and will 
make backporting patches easier in the future.

Other solution is to reverse the order again, but I think tagging the
renaming as a fix is OK for me here.

What do you think?
