The following commit has been merged in the master branch:
commit 351638e7deeed2ec8ce451b53d33921b3da68f83
Author: Jiri Pirko <jiri(a)resnulli.us>
Date: Tue May 28 01:30:21 2013 +0000
net: pass info struct via netdevice notifier
So far, only net_device * could be passed along with netdevice notifier
event. This patch provides a possibility to pass custom structure
able to provide info that event listener needs to know.
Signed-off-by: Jiri Pirko <jiri(a)resnulli.us>
v2->v3: fix typo on simeth
shortened dev_getter
shortened notifier_info struct name
v1->v2: fix notifier_call parameter in call_netdevice_notifier()
