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();
or
commandGate->runAction(someMethod);
In
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 ;-).
