From 515d54436e0da46d5f3250f682ee265e65ab303e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 18 Aug 2020 10:17:31 +0200 Subject: netlink: consistently use NLA_POLICY_EXACT_LEN() Change places that open-code NLA_POLICY_EXACT_LEN() to use the macro instead, giving us flexibility in how we handle the details of the macro.
