Do we want this in the uapi header? Even if this is useful, it might come with several drawbacks such as breaking scripts that parse kernel headers (and a quick git grep suggests we do have static inlines in headers, but in rather obscure ones) and breaking C89:
Let's please not say "C89" anymore, we've moved on! :)
The notes in [1], which is now nearly 2.5 years old, discuss the move to C11, and specifically how to handle the inline keyword.
I think it's quite clear at this point, that we should not hold up new work, based on concerns about handling the inline keyword, nor about C89.
