Apologies from my side for being too much of a patch-bot here.
I should have also given some more thought to the patch.
Atm, I'm sending this from Outlook, since [for some reason] the Linux mail-client isn't working.
[ Which is why this isn't properly inlined either ]

I'll send a V2.

It's a bad commit message, my fault. This should have been

Make sure that the trigger function stubs are all static inline.
Otherwise we might see compiler warnings about declared but unused functions.
