把IRP_MJ_CREATE失败后需要做其他处理么

在IRP_MJ_CREATE的完成例程中得到路径名，把该IRP失败掉，除了Irp->Status.status和information赋值并completerequest外，是否还需要手动发IRP_MJ_CLOSE的包下去把object 做close处理呢？还是系统会自动为create的file object做善后处理？
如果是把READ WRITE的IRP失败掉呢？
谢谢指点!!

There's no proper way of failing a CREATE IRP in completion routine especially if the CREATE IRP actually created a new file. You should move your logic into dispatch routine.

It's not good idea to deny READ or WRITE either. Deny them in CREATE.

michaelgz您的意思是：
Irp->Iostatus.Status = STATUS_ACCESS_DENIED;
Irp->Iostatus.Information = 0;
IoCompleteRequese(Irp,IO_NO_INCREMENT);
return status;
这种做法不能有效的令一个IRP失败么？谢谢
