This patch lifts the minimum supported libiscsi version from 1.4.0 to 1.9.0 since the BUSY patch required that change. On one this allows us to remove all #ifdefs from the code which makes the code easier to maintain and read. On the other hand I would not recommend libiscsi prior to 1.8.0 for production use because the following important libiscsi fixes for deadlocks and protocol errors are missing prior to 1.8.0: dbe9a1e SOCKET queue cmd PDUs directly in waitpdu queue 30df192 DATA-OUT set pdu->cmdsn appropriately 548bd22 ISCSI fix broken send logic in iscsi_scsi_async_command 14bee10 RECONNECT do not increase CmdSN for immediate PDUs 1f4a66a PDU queue out PDUs in order of itt. 562dd46 PDU avoid incrementing itt to 0xffffffff cd09c0f PDU use serial32 arithmetic for cmdsn, maxcmdsn and expcmdsn. 89e918e SOCKET validate data_size in in_pdu header 91267f5 Limit immediate and unsolicited data to FirstBurstLength Note that libiscsi 1.9.0 was released on Feb 24th, 2013, about one month after 1.8.0.
