Subject: [PATCH linux v3 0/1] Optimize network interfaces creation

When a lot of netdevices are created, one of the bottleneck is the creation
of proc entries. This serie aims to accelerate this part.

I'm not sure against which tree this patch should be done. I've done it against
linux.git.

v2 -> v3
 - restore credit to Thierry Herbelot for the initial idea.

RFCv1 -> v2
 - use a red-black tree instead of a hash list
