The end result is the same, but each commit passes
TDB_NO_FSYNC=1 buildnice make -j test TESTS=smb2.*lease
SOCKET_WRAPPER_KEEP_PCAP=1 FAIL_IMMEDIATELY=1 SMBD_DONT_LOG_STDOUT=1
SMBD_OPTIONS="-d10"
The last patch is not as small as possible, but I think it's ok.
Please have a look and push if you also happy.
