Merge branch 'inet-data-races'

Eric Dumazet says:

====================
inet: socket lock and data-races avoidance

In this series, I converted 20 bits in "struct inet_sock" and made
them truly atomic.

This allows to implement many IP_ socket options in a lockless
fashion (no need to acquire socket lock), and fixes data-races
that were showing up in various KCSAN reports.

I also took care of IP_TTL/IP_MINTTL, but left few other options
for another series.

v4: Rebased after recent mptcp changes.
  Added Reviewed-by: tags from Simon (thanks !)

v3: fixed patch 7, feedback from build bot about ipvs set_mcast_loop()

v2: addressed a feedback from a build bot in patch 9 by removing
 unused issk variable in mptcp_setsockopt_sol_ip_set_transparent()
 Added Acked-by: tags from Soheil (thanks !)
