RE: Close without IRP_MJ_CLOSE

Thanks for the replies.

It turns out that the IRP_MJ_CLOSE *is* being issued, however, it is
associated with a different process than the one that performed the
IRP_MJ_CREATE. Is this normal?

    Yes.
    It is because of Cc na/or Mm referencing for cached files.
    Thus when the last reference has gone - because of Mm's or
    Cc's issued ObDereferenceObject - there is IRP_MJ_CLOSE
    sent to File system. This is almost done in some system
    thread context.
