fd3fa5df34 qla2x00t-32gbit, target: Remove a kvfree() call 
Since the target code never assigns a value to se_sess->sess_cmd_map,
calling kvfree on that pointer is not necessary.

fc4c99dccd qla2x00t-32gbit: Upgrade initiator code to the code from kernel v5.1-rc2 
This patch is the output of git diff v4.18.20..v5.1-rc2 drivers/scsi/qla2xxx.
Only one manual change has been applied, namely the removal of
"cmd->se_cmd.map_cpu = cpu;" from qlt_alloc_qfull_cmd().

50bb06cc55 scst: Avoid that del_device suspends SCSI command processing 
scst_unregister_virtual_device() modifies scst_dev_list and removes
the LUNs associated with the virtual device being removed. Due to 
previous patches these actions can be performed safely without
suspending SCSI command processing. Hence remove the suspend and
resume activity calls from scst_unregister_virtual_device().
