Routine Description:
This is the single routine used to acquire file system resources. It
looks at the IgnoreWait flag to determine whether to try to acquire the
resource without waiting. Returning TRUE/FALSE to indicate success or
failure. Otherwise it is driven by the WAIT flag in the IrpContext and
will raise CANT_WAIT on a failure.
Arguments:
//

}
return TRUE;
}
//
// Despite the name this function may not always be called with lock held
// but if Unlock is TRUE, lock must be held.
