commit ce9d63d1618e1cd803e68a0d97ec352a8d125070
Author: Volker Lendecke <vl at samba.org>
Date: Sun May 22 14:16:46 2011 +0200
s3: Remove the smbtorture3 OPLOCK3 test
This is the last user of cli_receive_smb. Oplocks are nowadays tested
in smbtorture4, this mainly has historic value
commit 9a787bbad1f8a5b19242118fe7a37de76562edf8
Author: Volker Lendecke <vl at samba.org>

s3: Convert the OPEN4 test to async oplock handling
This removes a caller of cli_receive_smb
