This series introduces a new kernel configuration option NO_AUTO_INLINE,
which can be used to disable the automatic inlining of functions.
This will allow the function tracer to trace more functions
because it only traces functions that the compiler has not inlined.

Your series did the grve mistake of sending various patches only
to some recipients making it unreviewable.
But doing less and more explicitly inlining in general seems very
questionable.
