CVE description taken from the link above: An issue was discovered in 
the Linux kernel before 4.20. There is a race condition in smp_task_timedout() 
and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a 

Clean cherry pick. No context adjustments required. Compiled all architectures.
Boot-tested in an amd64 virtual machine and verified the module loaded

Regression potential: Low. This patch was released to bionic and cosmic
several months ago. It's been upstream since September 2018.
