Hi again, Chris and others!
We're hitting this again on 4.14.32.
Looks like the path iscsi_queuecommand -> prepd_reject/prepd_fault
results in iscsi_complete_task getting called with frwd_lock held
instead of the requisite back_lock which might explain the task list
corruption under heavy loads.

Hi Ilkka,
I was going through this particular issue reported here, which also seen
with Oracle Linux. I was curious to see the core for which you have posted
your below debugging.
Can I get the access to this particular core dump.
Regards,
Ashish

There's a rather long standing regression from commit
659743b [SCSI] libiscsi: Reduce locking contention in fast path
Depending on iSCSI target behavior, it's possible to hit the case in
iscsi_complete_task where the task is still on a pending list
(!list_empty(&task->running)). When that happens
