Agreed. Inlining avoided where possible.

Function split.

These functions are on a performance-critical path and they are called
exactly once - so the object's size isn't affected and having them inline
seems appropriate to me.

Will be checked.

Correct. It's gone.

Agreed to pass ret to upper layer, but we want to keep the error message.
Code modified accordingly.
