Can you please help me here.
Previously we said: gcc shall inline
Now we say: hi gcc - it is a good idea to inline this

But even without any inline annotation we would expect gcc
to inline it based on normal heuristics simply due to the
small size/footprint of the function.

So I cannot see how the CONFIG_OPTIMIZE_INLINING have any
effect here.
It all smells like a gcc bug to me.
