Seems that we already have a very similar patch from Lillian:

https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/init-mainc-check-if-rdinit-was-explicitly-set-before-printing-warning.patch
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/init-mainc-check-if-rdinit-was-explicitly-set-before-printing-warning-fix.patch

What's happening here?
