The numa_slit variable used by node_distance is available to a module as long as it is linked at compile-time. However, it is not available to loadable modules. Leading to errors such as: ERROR: "numa_slit" [drivers/nvme/host/nvme-core.ko] undefined! The error above is caused by the nvme multipath code that makes use of node_distance for its path calculation. When the patch was added, the lightnvm subsystem would select nvme and always compile it in, leading to the node_distance call to always succeed. However, when this requirement was removed, nvme could be compiled in as a module, which exposed this bug. This patch extracts node_distance to a function and exports it. Since ACPI is depending on node_distance being a simple lookup to numa_slit, the previous behavior is exposed as slit_distance and its users updated. Fixes: |
