There are two "initial patch", I wonder which one you mean.

There's his really first patch, which remoevs the lines in IP_GRE
which change dev->needed_headroom.  I was under the impression we
were against doing that.

The other patch he posted duplicates the device attribute variable
caching in two functions.

My patch is just a tweak so that we only do this sequence in one
place, the new sock_alloc_send_skb_reserve() helper, instead of
in both the ipv4 and ipv6 RAW code.

So I'm a little confused what your suggestion for rc10 really
is :-)
