I don't think I'm doing anything special for these kfuncs, so, in
theory, the rest of them should also have the same warning.
Should we add another __diag_ignore_all("-Wmissing-declarations", ...)
to kfuncs preamble?
I remember there was a discussion about introducing
BEGIN_KFUNC/END_KFUNC, but I don't think it went anywhere?
