That is true only if there are non-generic implementations of

real reason why this is needed.

This is a generic algorithm, the author Vitaly Chikunov has also confirmed
it, please consider this patch again.

As I said, the generic algorithm only needs to be loaded early *if*
there are non-generic implementations.

Cheers,


For ecrdsa, there is no reason to advance the initialization to subsys_init, this is just to make code clean up to have algorithm initialization uniform with other implementations.

It’s just that I think that in the commit c4741b230597 ("crypto: run initcalls for generic implementations earlier"), the modification to ecrdsa happened to be omitted, because from the point of commit time, it was submitted at the same time as the ecrdsa commits, and it may happen to be omitted for ecrdsa.
