Subject: [patch net-next V4 00/15] net: introduce upper device lists and remove dev->master
This is a V4 of a repost of my previous patchset:
"[patch net-next v2 00/15] net: introduce upper device lists and remove dev->master" from Aug 14
The discussion around
"[net-next] bonding: don't allow the master to become its slave"
forced me to think about upper<->lower device connections.
This patchset adds a possibility to record upper device linkage.
All upper<->lower devices are converted to use this mechanism right after.
That leads to dev->master removal because this info becomes redundant since
"master links" have the same value.
After all changes, there is no longer possible to do things as:
"bond->someotherdevice->samebond"
Also I think that drivers like cxgb3, qlcnic, qeth would benefit by this
in future by being able to get more appropriate info about l3 addresses.
v3->v4:
- comments in __netdev_upper_dev_link() squashed into one line
- kfree_rcu used instead of call_rcu in netdev_upper_dev_unlink()
v2->v3:
- removed recursion in __netdev_has_upper_dev()
- refreshed bits to be applicable on current net-next
v1->v2:
- s/unique/master/ better naming + stays closer to the past
- fixed vlan err goto
- original patch 15 (WARN_ON change) is squashed into the first patch
Jiri Pirko (15):
net: introduce upper device lists
macvlan: add link to upper device
vlan: add link to upper device
rtnetlink: remove usage of dev->master
team: remove usage of netdev_set_master()
bridge: remove usage of netdev_set_master()
netpoll: remove usage of dev->master
cxgb3: remove usage of dev->master
qlcnic: guard __vlan_find_dev_deep() by rcu_read_lock
qeth: ensure that __vlan_find_dev_deep() is called with rcu_read_lock
vlan: remove usage of dev->master in __vlan_find_dev_deep()
nes: remove usage of dev->master
bonding: remove usage of dev->master
net: remove no longer used netdev_set_bond_master() and
netdev_set_master()
net: kill dev->master
