NE_ERR_MEM_D...NT_NUMA_NODE(9)

💅 NE_ERR_MEM_DIFFERENT_NUMA_NODE(9) — like, the Kernel API Manual one, bestie 🎀

okay so picture this: it's a page from the Kernel API Manual and it's all about one (1) extremely specific error code. she's niche, she's iconic, and honestly? she ate. let's get into it ✨

✨ NAME ✨

NE_ERR_MEM_DIFFERENT_NUMA_NODE — the user space memory region is backed by pages from different NUMA nodes than the CPUs. 🫶

like literally. your memory is hanging out on one node and your CPUs are living their best life on another. different zip codes. not the vibe check we were hoping for 💀

🦋 SYNOPSIS 🦋

NE_ERR_MEM_DIFFERENT_NUMA_NODE

no arguments, no parameters, no little friends — just the code itself, standing there being a whole error 💅

ok but seriously bestie — if you're hitting this one, your pages and your CPUs are living on different NUMA nodes. that's the whole entire error. no cap 🔥

mwah, that's the page! 🧚 source lives at ./include/uapi/linux, dated October 2026, and the manual section is NE_ERR_MEM_D...NT_NUMA_NODE(9) — go forth and keep your memory and your CPUs on the same node, bestie, love u 💖🌸
