Thank you. Ah let me put this forward: please keep an eye on the (generic) queued_spin_lock() queued_spin_unlock() (just to point out an example). Their implementation (in part., the fast-path) suggests that if we will stick to RCsc lock then we should also stick to RCsc acq. load from RMW and rel. store. Andrea > > Alan >
