Subject: [PATCH v4 net-next 00/13] net: complete dev_base_lock removal

Back in 2009 we started an effort to get rid of dev_base_lock
in favor of RCU.

It is time to finish this work.

Say goodbye to dev_base_lock !

v4: rebase, and move dev_addr_sem to net/core/dev.h in patch 06/13 (Jakub)

v3: I misread kbot reports, the issue was with dev->operstate (patch 10/13)
    So dev->reg_state is back to u8, and dev->operstate becomes an u32.
    Sorry for the noise.

v2: dev->reg_state must be a standard enum, some arches
    do not support cmpxchg() on u8.

Eric Dumazet (13):
  net: annotate data-races around dev->name_assign_type
  ip_tunnel: annotate data-races around t->parms.link
  dev: annotate accesses to dev->link
  net: convert dev->reg_state to u8
  net-sysfs: convert netdev_show() to RCU
  net-sysfs: use dev_addr_sem to remove races in address_show()
  net-sysfs: convert dev->operstate reads to lockless ones
  net-sysfs: convert netstat_show() to RCU
  net: remove stale mentions of dev_base_lock in comments
  net: add netdev_set_operstate() helper
  net: remove dev_base_lock from do_setlink()
  net: remove dev_base_lock from register_netdevice() and friends.
  net: remove dev_base_lock
