Aw, it's small, here it is:

--- a/dlls/ntdll/file.c
+++ b/dlls/ntdll/file.c
@@ -1236,6 +1236,8 @@ static NTSTATUS server_ioctl_file( HANDLE handle, HANDLE
event,
         wine_server_set_reply( req, out_buffer, out_size );
         if (!(status = wine_server_call( req )))
             io->Information = wine_server_reply_size( reply );
+        else
+            io->Information = 0;

I wonder if it shouldn't also copy Information in the STATUS_MORE_ENTRIES
case, which is explicitly not a failure.
