There is still a build bug with the sock memcg code, that triggers
with !CONFIG_NET, that survived my series of randconfig builds.

Why are you undoing the static branch optimization?  That was a one of
the things that made me agree to even putting this code in.

Find a way to fix this without removing the static branch.

Dave,

I am not removing the static branch. This is just a macro, that expands 
to the static branch when the options are in place, and to 0 if they are 
not.

if (0) { } is certainly be removed to the compiler, so the code is out
anyway.
