This is the second fix for this .. The first was in this email (over a
month ago)

http://lkml.org/lkml/2007/8/31/318

The above was emailed to Thomas, but I also sent you that link in IRC as
a link of patches to include .. I'll be happy to audit my code better,
but you should also audit your inclusion process better.. There have
been too many missed patches, and too many double and triples fixes..
