Merge branch 'inet-implement-lockless-rtm_getnetconf-ops'

Eric Dumazet says:

====================
inet: implement lockless RTM_GETNETCONF ops

This series removes RTNL use for RTM_GETNETCONF operations on AF_INET.

- Annotate data-races to avoid possible KCSAN splats.

- "ip -4 netconf show dev XXX" can be implemented without RTNL [1]

- "ip -4 netconf" dumps can be implemented using RCU instead of RTNL [1]

[1] This only refers to RTM_GETNETCONF operation, "ip" command
    also uses RTM_GETLINK dumps which are using RTNL at this moment.
