From f40b6ae2b612446dc970d7b51eeec47bd1619f82 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Wed, 22 May 2019 20:27:55 -0700 Subject: ipv6: Move pcpu cached routes to fib6_nh rt6_info are specific instances of a fib entry and are tied to a device and gateway - ie., a nexthop. Before nexthop objects, IPv6 fib entries have separate fib6_info for each nexthop in a multipath route, so the location of the pcpu cache in the fib6_info struct worked. However, with nexthop objects a fib6_info can point to a set of nexthops (yet another alignment of ipv6 with ipv4). Accordingly, the pcpu cache needs to be moved to the fib6_nh struct so the cached entries are local to the nexthop specification used to create the rt6_info. Initialization and free of the pcpu entries moved to fib6_nh_init and fib6_nh_release. Change in location only, from fib6_info down to fib6_nh; no other functional change intended.
