The SYSINIT is the slow path. I've not tested yet but I bet M_WAITOK will be OK. So that we can guarantee that the root feeder is always available.

I think we could change to M_WAITOK in feeder_register() as well.

A nit here, you can assert, aka MPASS(feedercnt == 0), to ensure in future the change of order of SYSINIT will not break. The current change is absolutely OK, but just in case.

Good idea. Will commit the patch with the MPASS as well, but will the review here as-is here since it's accepted.

When making a non-functional change like this, it's nice to state why in the commit message.
