Hi Thomas & Harry,
This series addresses the two bugs that are cause a hung task to occur
when a long-standing I/O completes after both a ABORT_TASK, followed by
a iscsi-session reset occur, but before the subsequent I/O completion
by the backend of the aborted task takes place.
This results in multiple waiters on se_cmd->t_transport_stop_comp, and
only the first ABORT_TASK wait_on_complete() to occur. It also makes
sure that se_cmd descriptors associated with a TMR set CMD_T_ACTIVE
before dispatch to ensure that transport_wait_for_tasks() works as
expected for TMRs as well.
Finally, it fixes a iscsi-target specific bug where iscsi_queue_req
memory was being leaked during the same ABORT_TASK + session reset
case, causing a iscsi_qr_cache warning upon iscsi_target_mod unload.
Please test!
