Gregory Price started his session in the memory-management track of the
2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit by saying that, in
current kernels, if a NUMA node has memory, the assumption is that anybody can
make use of it. He is trying to implement the opposite policy — to make
some memory off-limits for all processes except those designed specifically
to use it. The session was used to present his goals and to discuss how
they might be implemented.
