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
So just these 2 commits? In which order?
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/"
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.
Now queued up, thanks.
