crash in iscsi/scsi initiator with linux-4.15.0-rc1

Hey, I'm seeing this null pointer dereference with linux-4.15.0-rc1. To reproduce it, I connect two ram disks via iscsi/TCP, and start an fio: iscsiadm -m discovery --op update --type sendtargets -p 172.16.1.10:3260 iscsiadm -m node -p 172.16.1.10:3260 -l ISCSI_DISKS=/dev/sdd:/dev/sde; fio

Re: [PATCH] bsg: update bsg_device_list to utilize static hash table implementation.

This patch was submitted as an effort to standardize on Sasha's hashtable implementation. Just a friendly ping to get some comments on this patch, been about 2 months with no comments on it at all. Are there any changes to be requested or issues raised with this change?
