From: Jiri Pirko <j...@mellanox.com>
Some drivers, like mlxsw, are not interested in notifications coming in
for netdevices from other network namespaces. So introduce per-netns
notifiers and allow to reduce overhead by listening only for
notifications from the same netns.
This is also a preparation for upcoming patchset "devlink: allow devlink
instances to change network namespace". This resolves deadlock during
reload mlxsw into initial netns made possible by
328fbe747ad4 ("net: Close race between {un, }register_netdevice_notifier() and
setup_net()/cleanup_net()").
Jiri Pirko (3):
net: push loops and nb calls into helper functions
net: introduce per-netns netdevice notifiers
mlxsw: spectrum: Use per-netns netdevice notifier registration
