Either way works correctly, I don't care much, but picked the __init
annotation as it seemed more intuitive. If the compiler decides to
make it out-of-line for whatever reason, I see no point in telling it
otherwise, even though I agree it is a bit silly.

Should I send the patch with __always_inline?
