[PATCH net-next 0/2] macvlan: RTNL-less macvlan_fill_info()

[Eric Dumazet <edumazet@google.com>]

This series removes the RTNL lock dependency from macvlan_fill_info(),
allowing it to run under RCU read lock.

The first patch annotates data races on 'mode' and 'flags' fields which
are accessed locklessly in the RX/TX paths.

The second patch transitions macvlan_fill_info() to RCU, adding necessary
annotations for other fields and handling concurrent updates to the MAC
address list by computing the count dynamically.

Eric Dumazet (2):
  macvlan: annotate data-races around vlan->mode and vlan->flags
  macvlan: no longer rely on RTNL in macvlan_fill_info()
