The fix I was referring to is: commit 5e2c956b8aa24d4f33ff7afef92d409eed164746 Author: Nicholas Bellinger <[email protected]> Date: Wed May 25 12:25:04 2016 -0700 target: Fix missing complete during ABORT_TASK + CMD_T_FABRIC_STOP It's carried in v4.8+ and was also flagged for 3.14+ stable inclusion, so should be present in many distro kernels by now. That said, there have been many other changes in this area.
