Date: Fri, 19 Feb 2021 15:25:12 +0530	[thread overview]
Message-ID: <20210219095510.GA24256@chelsio.com> (raw)

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/drivers/nvme/host/rdma.c?h=v5.10.17#n863)

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.
