--- Comment From mranw...@us.ibm.com 2019-08-30 01:32 EDT--- It works on the -proposed kernel for xenial. I'm not sure if I was hitting the issue on the -159 kernel, but the test does pass now.

--- Comment From hb...@us.ibm.com 2019-05-20 15:29 EDT--- We need this fix in 18.04.X. Without these patches, 842 compression is broken which can affect zswap or other workloads that can exploit HW compression.
