In my original use case, yes crc32c_generic is added to the initrd:
lsinitramfs /boot/initrd.img-4.14.36-test |grep crc32c
lib/modules/4.14.36-test/kernel/arch/x86/crypto/crc32c-intel.ko
lib/modules/4.14.36-test/kernel/crypto/crc32c_generic.ko
Note that I do not build libcrc32c at all. I personally prefer the way
it was while changing my kernel config to building-in my choice of
crc32c drivers. That way I don't have an unused module floating around.
I can, however, see that this patch might be a better choice for
distributions.
This has been fun,
