The following kernel warnings are noticed on x86 devices while booting the Linux next-20240603 tag and looks like it is expected to warn users to use NUMA_NO_NODE instead.
Usage of MAX_NUMNODES is deprecated. Use NUMA_NO_NODE instead
The following config is enabled CONFIG_NUMA=y
I am seeing this as well. Is the following commit premature?
e0eec24e2e19 ("memblock: make memblock_set_node() also warn about use of MAX_NUMNODES")
Maybe old ACPI tables and device trees need to catch up?
Left to myself, I would simply remove the WARN_ON_ONCE() from the above commit, but I would guess that there is a better way.
Well, the warning is issued precisely to make clear that call sites need to change. A patch to do so for the two instances on x86 that I'm aware of is already pending maintainer approval.
