That's fine as I think this whole approach is wrong to begin with.

We are not doing a tree wide change at rc4 just to scratch an itch which
is there for ages and has been debated for months.

Q: Did you try a merge of the result against -next?
A: Definitely not.

The proper approach is to provide all the infrastructure, i.e. the new
interfaces and merge them during the next merge window. Right before rc1
provide a script or a script converted tree to Linus which switches the
tree over to the new world order.

How long have you been around doing kernel development and how much fuzz
do you make about even trivial changes to ftrace?

Thanks,
