This series better handles some PCI HyperV error cases in general and for kdump case. Some of review comments from previous individual patch reviews, including splitting into separate patches, have already been incorporated. Thanks Lorenzo Pieralisi for the review and suggestions, as well as Michael Kelley's contribution to the commit log. Thanks, Wei Wei Hu (2): PCI: hv: Fix the PCI HyperV probe failure path to release resource properly PCI: hv: Retry PCI bus D0 entry when the first attempt failed with invalid device state drivers/pci/controller/pci-hyperv.c | 60 ++++++++++++++++++++++++++--- 1 file changed, 54 insertions(+), 6 deletions(-)Applied to pci/hv, thanks.Lorenzo -- Will you be bringing these fixes into 5.7? The main fix is the 2nd patch, but there wasn't a clear "Fixes:" tag to add because the problem is due more to how Hyper-V operates than a bug in a previous Linux commit. We have a customer experiencing the problem, so getting the fix into the main tree sooner rather than later is helpful.
We usually send fixes at -rc* if the bug was introduced in the previous release, at the moment this is v5.8 material not planned for such a late -rc* (ie -rc7). We can send patches to stable and/or apply a Fixes: tag if that can help when the commits hit mainline. Lorenzo
