Partially survives samba.tests.reparsepoints.ReparsePoints.test_create_reparse NTTRANS-FSCTL needs changing: Windows 2016 returns INVALID_BUFFER_SIZE instead of our NOT_A_REPARSE_POINT. This is not the whole story, but this smbtorture3 change makes autobuild survive. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
