ChangeLog: * allow NtFileFlushBuffers to block, as flushing a named pipe requires this
what I don't like in your patch is that you create an event in all cases, where according to the doc, FlushFileBuffers should only block for named pipes.
maybe, it would be better to return the event handle from the flush server call and wait in kernel if this event is not NULL
