Re: [PATCH 1/8] ftrace: Replace uses of _ftrace_direct APIs with _ftrace_direct_multi

Looking at samples/ftrace/, as of this patch we have a few samples that are
almost identical, modulo the function being traced, and some different register
shuffling for arguments:

* ftrace-direct.c and ftrace-direct-multi.c
* ftrace-direct-modify.c and ftrace-direct-modify

... perhaps it would be better to just delete the !multi versions ?

The multi versions hook two functions and the !multi hook just one but
I agree that this granularity in coverage is probably just a
maintenance burden and doesn't help with much! :)
I'll delete the !multi in v2, as part of the patch 2 and patch 1 will
just migrate the selftest to use the multi API.
