Subject: [PATCH net-next 0/9] inet: shrink netns_ipv{4|6}

From: Eric Dumazet <edumazet@...gle.com>

This patch series work on reducing footprint of netns_ipv4
and netns_ipv6. Some sysctls are converted to bytes,
and some fields are moves to reduce number of holes
and paddings.

Eric Dumazet (9):
  inet: shrink inet_timewait_death_row by 48 bytes
  inet: shrink netns_ipv4 by another cache line
  ipv4: convert fib_notify_on_flag_change sysctl to u8
  ipv4: convert udp_l3mdev_accept sysctl to u8
  ipv4: convert fib_multipath_{use_neigh|hash_policy} sysctls to u8
  ipv4: convert igmp_link_local_mcast_reports sysctl to u8
  tcp: convert tcp_comp_sack_nr sysctl to u8
  ipv6: convert elligible sysctls to u8
  ipv6: move ip6_dst_ops first in netns_ipv6
