Hi Greg, I'm waiting on the fixes to the ATM layer (coming soon to a kernel
near you). As for the position of MOD_INC_USE_COUNT, did you ever hear
of anyone getting bitten by a race like this? If it makes you feel better, I
will move it up, probably just before I take the semaphore (since that is the
first place we can sleep). I will do it tomorrow, OK?

All the best,

Duncan.
