From 88ab31081b8c8d4d7698711b80fbfd3f52d27fd9 Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Tue, 8 May 2018 09:07:03 -0700 Subject: net/udp: Update udp_encap_needed static key to modern api No changes in refcount semantics -- key init is false; replace static_key_enable with static_branch_enable static_key_slow_inc|dec with static_branch_inc|dec static_key_false with static_branch_unlikely Added a '_key' suffix to udp and udpv6 encap_needed, for better self documentation.
