Whether the API is better is debatable. As I said, almost no drivers use
the new XArray interface, and perhaps partly because the new interface
isn't as intuitive as has been claimed (e.g. xa_load() instead of
ida_find()). And IDR/IDA isn't marked/documented as deprecated as far as
I know.

I can't just slap a 'deprecated' attribute on it.  That'll cause a
storm of warnings.  What would you suggest I do to warn people that
this interface is deprecated and I would like to remove it?

Why do you think that idr_find() is more intuitive than xa_load()?
The 'find' verb means that you search for something.  But it doesn't
search for anything; it just returns the pointer at that index.
'find' should return the next non-NULL pointer at-or-above a given
index.
