I am sorry, I made a mistake
I verified that the patch was in my nf-next-2.6 clone
but I was running Dave Millers net-next-2.6...
I will switch to nf-next-2.6 and run my tests again
(with the patch included)
Anyway you was right, usecnt is at offset 0x24 on my 64 bit machine.
I will post the results today or to morrow.
