From 48526a0f4ca2b484cab4318dc0b2c2be1d8685b7 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 2 Oct 2020 14:49:57 -0700 Subject: genetlink: bring back per op policy Add policy to the struct genl_ops structure, this time with maxattr, so it can be used properly. Propagate .policy and .maxattr from the family in genl_get_cmd() if needed, this way the rest of the code does not have to worry if the policy is per op or global.
