Dave Miller (networking maintainer) applied your patch to his various
trees on March 13th.  Since 2.6.29 was in bug-fix only mode at that
time, your patch was too late to be included 2.6.29.  It has just been
merged into Linus' linux-2.6 tree [1] (which will become 2.6.30) via
Dave Miller's tree.  So it appears your patch will be included in the
2.6.30 kernel when that is released.

If you think your patch is regression-free and appropriate for stable
kernels (2.6.27, 2.6.28, etc) you might try to send it to the stable
team for inclusion in subsequent stable kernel updates.
