Title:
  Request to revert SAUCE patches in the 18.04 SRU and update with
  upstream version

Bug description:
  == SRU Justification ==
  This SRU was requested by IBM.  It contains one SAUCE patch and three
  commits from linux.next.

  IBM requested that we revert a set of SAUCE patches from 18.04 and
  replace them with patches from linux-next.  Based on review comments,
  there has been minor changes from the original SAUCE patches and the
  versions in linux-next.

  The first SAUCE patch contains all the changes between the current version
  of SAUCE patches for latest cxlflash patches in bionic and the latest
  version accepted by the community. This only has the needed changes and
  makes it so we don't have to revert and re-apply a high number of patches.
  In addition to the SAUCE patch, IBM requested the 3 additional new patches
  from the linux-next tree.

  == Fixes ==
  UBUNTU: SAUCE: (no-up) cxlflash: OCXL diff between v2 and v3
  a3feb6ef50de ("scsi: cxlflash: Synchronize reset and remove ops")
  9a597cd4c0ce ("scsi: cxlflash: Remove commmands from pending list on timeout)"
  d2d354a606d5 ("scsi: cxlflash: Handle spurious interrupts")

  == Regression Potential ==
  Medium.  All the patches are specific to the cxlflash driver, but there
  are four of them and one is a SAUCE patch.

  == 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.

I was able to install the kernel and run regression. It looks good.

I do have 7 more patches that were added recently to upstream for
cxlflash. We would like to have them included in bionic SRU as well.
Details are given below. Please let me know if you can apply on top of
this using this bugzilla or if you want me to open a new request for the
same.

version accepted by the community. This only has the changes for the 3 
differences updated earlier. After applying this diff patch, please apply the 3 
additional new patches from the next/master tree. The 3 patches needed on top

I will work on the diff patch and you can apply it as additional SAUCE patch to 
come up to speed with the version we have in next/master and then apply the 3 
new patches. I will update the BZ when the SAUCE patch with the diff is ready. 
Thanks !!

Can you please clarify that you have replaced the reverted patches with the 
patch from next/master tree ? I have provided the replacement commits for each 
of the revert request. Can you please confirm if this is done ?

I looked through the attachments. The reverts are not clean. It has
reverted more than it should. But I doubt if you can selectively revert
those patches because the following patches are built on top of it.

I think easiest and cleanest solution might be to revert all the
cxlflash SAUCE patches and apply the ones from next/master. Another
option is for me to create a new patch with just the differences. Please
let me know what you recommend.

Below are the SAUCE patches to be reverted with the relevant commits (listed 
below each SAUCE patch) from next/master tree. Please note that the commit IDs 
in next/master is subject to changes when it is rebased. But the patch 
description should stay the same. Below are the current commit IDs.

Also, there is a possibility to see merge conflicts since selective
patches are being reverted in the series. If you face issues, please let
me know how I can help.

requests are also listed at the end of the comment.
