net: Fix fib notifer to return errno (c30d9356) · Commits · 戴 / test

Notifier handlers use notifier_from_errno to convert any potential error to an encoded format. As a consequence the other side, call_fib_notifier{s} in this case, needs to use notifier_to_errno to return the error from the handler back to its caller. Signed-off-by:
