Hi,
I recently wrote a script which identifies patches potentially missing
in downstream kernel branches. The idea is to identify patches backported/
applied to a downstream branch for which patches tagged with Fixes: are
available in the upstream kernel, but those fixes are missing from the
downstream branch. The script workflow is something like:
- Identify locally applied patches in downstream branch
- For each patch, identify the matching upstream SHA
- Search the upstream kernel for Fixes: tags with this SHA
- If one or more patches with matching Fixes: tags are found, check
if the patch was applied to the downstream branch.
- If the patch was not applied to the downstream branch, report
Running this script on chromeos-4.19 identified, not surprisingly, a number
of such patches. However, and more surprisingly, it also identified several
patches applied to v4.19.y for which fixes are available in the upstream
kernel, but those fixes have not been applied to v4.19.y. Some of those
are on the cosmetic side, but several seem to be relevant. I didn't
cross-check all of them, but the ones I tried did apply to linux-4.19.y.
The complete list is attached below.
Question: Do Sasha's automated scripts identify such patches ? If not,
would it make sense to do it ? Or is there some reason why the patches
have not been applied to v4.19.y ?
Thanks,
Guenter
