Pulled, thanks!

Please double check the use of the spin lock in patch 3. Stats are
updated in an atomic context when read from /proc, you probably need 
to convert that spin lock to _bh.

Thanks Jakub. I'll look into it.

I just did some tests with lockdep enabled, reading from /proc/net/dev
in a loop, and everything seems fine. Am I missing something?

Indeed /proc only takes the RCU lock so you should be fine, thanks
for checking.
