[infiniband] IB/core: Fix potential NULL pointer dereference in pkey cache
If a kernel ships with this patch, it needs the 1st patch. |
[Impact]

[infiniband] IB/core: Fix potential NULL pointer dereference in pkey cache
If a kernel ships with this patch, it needs the 1st patch.
[Test Case]
Boot the current 5.4 linux-azure kernel from focal-updates (5.4.0-48.52) on an Azure instance with a mlx4 device without RoCE support, the devices are wrongly ignored.
The expected result is that those devices are created an available.
[Regression Potential]
A potential regression would only affect instances running the linux-azure 5.4 kernels with mlx4 devices. |
