Subject: 4.4.10 lio (iscsi_trx) messages in dmesg

I'm seeing the following message when using the lio iscsi target. This
message is on the machine with the target. I have 1 target with 3 luns.
The luns are /dev/sr0 1 and 2 using pscsi backend. On the initiator, I
issue eject srX for each of the 3 drives and see this message. (NOTE: The
initiator's kernel is 3.12.52 and doesn't show any messages)

That patch doesn't apply to 4.4.10. The 2nd hunk was rejected.
