From: Grant Likely <redacted>

Hey Ben and Kumar,

Just found this while testing some unrelated changes.  Technically
this is a bug fix that should go into 2.6.29, but it looks like an
old problem and probably nobody is getting bitten by it.  I don't
think the world is going to end if it misses the 2.6.29 release.
