Hi All,
Below commits needs to be backported to 5.10.y kernels to avoid NULL pointer deref panic(while trying to access 'numa_node' from NULL 'dma_device'), @ Line: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/driver...)
commit:22dd4c707673129ed17e803b4bf68a567b2731db commit:8ecfca68dc4cbee1272a0161e3f2fb9387dc6930
The panic is observed at nvme host(provider/transport being SoftiWARP), while perfroming "nvme discover".
Hence, please backport the below patch series to '5.10.y' kernel. "https://lore.kernel.org/linux-iommu/20201106181941.1878556-1-hch@lst.de/"
Thanks, Krishnamraju.

So just these 2 commits? In which order?

What are the git commit ids of these patches in Linus's tree and have you tested them to ensure that they work? Why this 10 patch series and not the 2 above? Or is this a different request?
confused,

Hi Greg,
Sorry for the confusion, I didn't know that I can request for the backport of selected patches in a patch series. As I don't have much background & testing feasability of other patches, I request you to backport only below two patches(same order as below):
commit#1:8ecfca68dc4cbee1272a0161e3f2fb9387dc6930 RDMA: Lift ibdev_to_node from rds to common code author: Christoph Hellwig hch@lst.de
commit#2:22dd4c707673129ed17e803b4bf68a567b2731db nvme-rdma: Use ibdev_to_node instead of dereferencing ->dma_device author: Christoph Hellwig hch@lst.de
And I belive these two patches has no dependency with other patches in the series. I've tested, it's working fine.
Thanks, Krishnamraju.
