** Summary changed:
- Request to backport cxlflash patches to 16.04 SRU
+ Request to backport cxlflash patches to 16.04 HWE Kernel
** Description changed:
- ---Problem Description---
- We have few cxlflash patches upstream that we would like to be included in
the Ubuntu 16.04 HWE kernel. Below patches are in next/master lined up for 4.15
kernel.
+ == SRU Justification ==
+ IBM is requesting these three cxlflash patches in the Ubuntu 16.04 HWE and
newer
+ kernels. All three patches have now landed in mainline v4.15-rc1.
- 285e6670d0229b0157a9167eb8b2626b445a5a0e scsi: cxlflash: Use derived maximum
write same length
- 0d4191305e69e42b3f7f11bbcf077d1d42929f94 scsi: cxlflash: Allow cards without
WWPN VPD to configure
- d84c198f43c50c6c0bd57571acbf0f000165bd56 scsi: cxlflash: Derive pid through
accessors
+ These commits fix bugs in the existing code - missing VPN could disable a
+ card and the write same sector size.
- Please let me know if there are questions/concerns.
+ == Fixes ==
+ 285e6670d022 ("scsi: cxlflash: Use derived maximum write same length")
+ 0d4191305e69 ("scsi: cxlflash: Allow cards without WWPN VPD to configure")
+ d84c198f43c5 ("scsi: cxlflash: Derive pid through accessors")
+
+ == Regression Potential ==
+ Medium. These patches are not limited to one arch, but they are limited to
cxlflash.
+
+ == Test Case ==
+ A test kernel was built with these patches and tested by the original bug
reporter.
+ The bug reporter states the test kernel resolved the bug.
