Oh, well.. that too, true. Thanks John!

Yup, and these patches are all fine. John is just saying that some
removed functions are still used by the persistent_ftrace code, which
is out-of-tree (it is in Android kernel git tree only).

But we're going to replace persistent_ftrace by pstore/ftrace, and
the patches were posted already; so functinality-wise, we didn't
lose anything.

Thanks,
