Looks like a PSCSI specific NULL pointer dereference when reading the
dev_type attribute if a backend device was not able to be successfully
configured -> enabled.
Here's a quick patch to address this case. Please confirm on your end.
Thanks for reporting!

Unfortunately I can not reproduce it anymore. Maybe it depends on the .config?

So the way to reproduce is to read the scsi_lu/dev_type configfs
attribute when a PSCSI backend device has not yet been configured ->
enabled. Eg:
root@scsi-mq:/usr/src/target-pending.git# modprobe target_core_mod
root@scsi-mq:/usr/src/target-pending.git# mkdir -p /sys/kernel/config/target/core/pscsi_0/foo/
root@scsi-mq:/usr/src/target-pending.git# cat /sys/kernel/config/target/core/pscsi_0/foo/statistics/scsi_lu/dev_type
Killed
I've confirmed the previous patch addresses this case, which now returns
TYPE_NO_LUN. (0x7f)
root@scsi-mq:/usr/src/target-pending.git# modprobe target_core_mod
root@scsi-mq:/usr/src/target-pending.git# mkdir -p /sys/kernel/config/target/core/pscsi_0/foo
root@scsi-mq:/usr/src/target-pending.git# cat /sys/kernel/config/target/core/pscsi_0/foo/statistics/scsi_lu/dev_type
127
Queuing up this patch to target-pending/master now, and including a CC'
to stable as well.
Thank you,
