From c30d9356e9e8ed0735c1215e187b03d3ae8b4966 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 27 Mar 2018 18:21:55 -0700 Subject: [PATCH] net: Fix fib notifer to return errno 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.
