I removed the section you originally refererd to as it was associated with the
linux 2.4 support which was also removed.

I asked if the remaining section (above) was acceptable so we could retain our
buffer recycling which enhances throughput. I never received a rely so it was
left in my last patch.

The above comment now answers my part of my initial question. Are you aware of
a better way to implement this or must we lose all our recycling enhancements?

Thanks,
