Routine Description:
This is the common routine for closing a file/directory called by both
the fsd and fsp threads.
Close is invoked whenever the last reference to a file object is deleted.
Cleanup is invoked when the last handle to a file object is closed, and
is called before close.
The function of close is to completely tear down and remove the fcb/dcb/ccb
structures associated with the file object.
Arguments:
Fcb - Supplies the file to process.
Wait - If this is TRUE we are allowed to block for the Vcb, if FALSE
then we must try to acquire the Vcb anyway.
VcbDeleted - Returns whether the VCB was deleted by this call.
Return Value:
NTSTATUS - The return status for the operation

Routine Description:
This routine is called to update the Scb/Fcb to reflect the changes to
a file through the fast io path. It only called with a file object which
represents a user's handle.
Arguments:
FileObject - This is the file object used in the fast io path.
Scb - This is the Scb for this stream.
CheckTimeStamps - Indicates whether we want to update the time stamps from the
fast io flags as well. This will be TRUE if our caller will update the standard information,
attribute header and duplicate info. FALSE if only the attribute header and duplicate info.
The latter case is the valid data length callback from the cache manager.
Return Value:
None.
