When debugging a race condition in scsi_remove_target of 3.12, I ran into this
possible bug within scsi_alloc_target.
When an existing "struct scsi_target" is found and used, the starget just got
through kzmalloc should be freed, rather than dong a "put_device(dev)".
diff --git a/drivers/scsi/sc
I ran into a series of crashes within scsi_remove_target in SUSE 12 SP1
(3.12.49-11-default). This will happen very easily if there is a lot of disks
with many storage and host FC ports. It occurs when all the ports are timeout
at the same time. 50 disks for each rports (the same 50 LUNs), 4 rpo
