Subject: [PATCH v1 net-next 0/7] ipv6: Follow up for RTNL-free RTM_NEWROUTE series.

Patch 1 removes rcu_read_lock() in fib6_get_table().
Patch 2 removes rtnl_is_held arg for lwtunnel_valid_encap_type(), which
 was short-term fix and is no longer used.
Patch 3 fixes RCU vs GFP_KERNEL report by syzkaller.
Patch 4~7 reverts GFP_ATOMIC uses to GFP_KERNEL.


Kuniyuki Iwashima (7):
  ipv6: Remove rcu_read_lock() in fib6_get_table().
  inet: Remove rtnl_is_held arg of lwtunnel_valid_encap_type(_attr)?().
  ipv6: Narrow down RCU critical section in inet6_rtm_newroute().
  Revert "ipv6: sr: switch to GFP_ATOMIC flag to allocate memory during
    seg6local LWT setup"
  Revert "ipv6: Factorise ip6_route_multipath_add()."
  ipv6: Pass gfp_flags down to ip6_route_info_create_nh().
  ipv6: Revert two per-cpu var allocation for RTM_NEWROUTE.
