Re: [PATCH] LSM networking: skb hooks for 2.5.42 (2/7)

["David S. Miller" <davem@xxxxxxxxxx>]

There is no way in hell that you are going to
add a function call for every time we set the
socket owner of a SKB.

That is a critical path and it happens millions upon
millions of times a second on a busy server.  Performance
will be penalized by changes like this.

I want all this junk #ifdef'd if it is necessary, in particular
the new member added to sk_buff et al.  There is no way this stuff
is going to happen in the default build, at least not in my networking
tree :-)
