Subject: [PATCH v3 0/2] Fix uevent race in register_netdevice()
I'm trying to fix a race in register_netdevice(). The problem is that
there's a uevent to userspace before the netdevice is ready for use. The
problem is described here:
https://bugzilla.kernel.org/show_bug.cgi?id=15606
I have sent few different ways to fix this, but none of them have been
really usable. Now I came up with a way which changes the driver core
to make it possible send the uevent in a separate call. This is a clean
and safe way to fix the race. Downside is that two new functions are
added to the driver core interface.
Please comment.
