---Problem Description---
Recently a regression in cxlflash driver was identified and a fix has been upstreamed to kernel.org. We would like to get that included in Xenial 16.04.3 SRU (HWE v4.10 kernel). Even though regression patch is the very last one, I have also listed the missing patches in-between, that are minor and will be easier for further cxlflash updates to Xenial.
