I have a driver that it is a filesystem filter driver.


Its fsd filter device above th bdfsfltr.


When IO MANAGER send IRP_MJ_CRRATE to the top of fsd device stack,my fsd filter device will call ZwCreateFile,cause a IRP_MJ_CREATE to lower device,reach to bdfsfltr. Then bdfsfltr will get the name of the file that send IRP_MJ_CREATE to the top of fsd device stack.


As you can see,Reentrant had happened.


Can you confirm the question?

    Hi


    Sorry for the delayed reply.


    I didn't understand your question.


    Could you rephrase it? Also, please provide more details about the machine and operating system.


    Thank you.
