Sorry if I'm being daft, but what did you refer to be "an existing
option"? there was no CONFIG_EBOIV before my patchset, it was simply
built as part of dm-crypt so it seems that setting CONFIG_EBOIV
default to dm-crypto Kconfig option value does solves the problem, or
have I missed something?

Thanks,
