[PROPOSED PATCH] ATM refcount

From: Rogier Wolff (R.E.Wolff@BitWizard.nl)
Date: Thu Oct 19 2000 - 08:15:07 EST


Hi All,

Could you take a look at this patch for the atm reference counting and
locking problems? I think this will fix these problems. But I could
have missed someting. Please ignore the "firestream" parts. They are
for an other driver (which will come later).

        Patrick
