Ehe... and this is the reason why: The code was added by this patch:
commit 0e3638d1e04040121af00195f7e4628078246489
Author: Dave Hansen <haveblue@xxxxxxxxxx>
Date: Thu Mar 16 17:30:16 2006 -0800
warn when statically-allocated kobjects are used
..which only exists in -next. Is that just a truly ancient patch, or
did somebody forget to adjust their clock?
(Stephen: Maybe this has been answered before, but what's the best way
