[Fault-injection-developer] Why use fi.h and fi_internel.h?

[Rusty L. <ru...@li...>]

Is there a good reason for having both a fi.h and
a fi_internal.h?  I know we use to expose a header file
for user space apps to use back when user/kernel interaction
happened with ioctls, but now there is no reason any non-kernel
code would need to use our header file.
