Name functions that aren't exposed outside of a file with '_' prefix and
make sure that all verbs ops' implementations are named according to the
op name with an additional 'efa_' prefix.

That isn't the kernel convention, please don't use _ like this

AFAIK there is no single kernel convention for static functions naming 
and it also seems that the underscore prefix isn't rare in the subsystem.

Would you suggest a preferred style?

Underscore at the beginning of the function name is a common practice
to mark that function as locked variant.

Thanks

Yeah, it is not typical to mark static functions at all.

You might exclude the symbol prefix (like efa_) but even that is not
universal.
