[Impact]
* mdadm as shipped in 18.04.0 does not support Intel VROC arrays, as to be shipped over Bionic LTS lifecycle in multiple laptop/desktop/server SKUs by multiple OEMs.
* this is a request to backport mdadm master, with support of Intel VROC arrays, and subsequent compiler fixes, and reshaping fixes, to fully support VROC arrays (including reshaping).
[Test Cases]
* Ensure existing Intel IMSM raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
* Ensure existing linux raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
- with 0.90 metadata; 1.0 metadata; 1.1 metadata; 1.2 metadata
* [Optional] ensure that DDF raids continue to assemble, boot, shutdown cleanly, bootable when degraded.
* Validate installers onto Intel IMSM raids
* Validate installers onto Linux RAID
[Regression Potential]
* Worst case scenario is failing to start assembled array in rw mode, on boot. This would result in dropping into emergency shell/mode in either initramfs, or emergency.target requiring manual intervention by a sysadmin to recover and start synced raid array. However, the test cases above should cover this regression potential adequately.
* Other changes, to resizing/reshaping may result in failure to resize/reshape, but these are rare maintenance operations for which one should have a backup - or able to recover from such an operation.
