  I couldn't get the exploit to work for 2.6.10 either.  First there's
changing a struct in it to user_desc to make it compile, then it just
SEGVs all the time here.
  This is quite apart from the fact it's trying to exploit a race
condition and as such can take a lot of attempts in a loop to actually
work anyway (must have hit it on the 50th or more iteration on my 2.4.28
machine).
  Anyone got working exploit code for 2.6.10 ?
