[in] PDRIVER_OBJECT DriverObject,
[in] PDRIVER_FS_NOTIFICATION DriverNotificationRoutine
);
Parameters
[in] DriverObject
Pointer to the driver object for the filter driver.
[in] DriverNotificationRoutine
A pointer to the PDRIVER_FS_NOTIFICATION routine, which the file system calls when it registers or unregisters itself.

Remarks
IoUnregisterFsRegistrationChange unregisters a file system filter driver's notification routine so that it is no longer called whenever a file system calls IoRegisterFileSystem or IoUnregisterFileSystem.
