FastIoDispatch

Hello!

This question is a beginner question, just for understanding purpose.

Assume a filter driver, that only attaches to FS-recognizers (just for
watching IRP_MN_MOUNT_VOLUME and IRP_MN_LOAD_FILE_SYSTEM activity). Should I
fill the FastIoDispatch-structure? Or can I set this to NULL without getting
into trouble?

Thanks in advance
Frank
