Duane --

Recompiling my kext for Leopard has revealed that IOSyncer is entirely
deprecated.

Is there a replacement? What should be done instead?

Some variation of either IOCommandGate::runAction + IOCommandGate::commandSleep()/commandWakeup() on the completion path, or IOLockLock()/IOLockSleep()/IOLockWakeup()/IOLockUnlock(), whichever is more convenient. Typically, you have something like:

IOLockLock();

while ( !notDone )

{

IOLockSleep();

}

IOLockUnlock();

commandGate->runAction(someMethod);

object::someMethod()

{

while ( !notDone )

{

commandGate->commandSleep();

}

And the completion routine would call commandGate->commandWakeup().

Hope this helps.

It appears that IOStorage still necessarily uses IOSyncer, so it can't
be too far gone. :-)

It will be fixed in due time ;-).
