+"What makes this interesting (and is the reason this doesn't fail
+ normally) is that these functions are all called within kernel_init, so
+ the __ro_after_init attribute shouldn't have caused the variable to be
+ read-only yet."
+
+When ftrace starts, it needs to set the kernel text to write, and when
+it finishes it sets it back to readonly. But the kernel is not set to
+readonly at boot up.
+
+Can you test this patch? (Warning, I didn't even compile test it)
