Update Sunday: I have been doing a little checking, and insmod looks by
default in /lib/modules/kernel-version/fs. The module xfs.o is already
there by default. Therefore simply "insmod xfs.o" would work in startarla.
Clearly, either the rpm spec file or startarla need to be modified. I am
not sure which.

The good news is that the kernel module xfs.o loads and unloads without
fuss.
