💖 numa_fill_memblks(9) 💖

okay so bestie, welcome to the Kernel API Manual page for numa_fill_memblks — yes that's the whole title, we're being official today 💅

✨ NAME ✨

numa_fill_memblks — fill in the gaps in numa_meminfo memblks 🧩

🌸 SYNOPSIS 🌸

int numa_fill_memblks (u64 start , u64 end );

🎀 ARGUMENTS 🎀

• start — the address where the fill begins, like, the starting line 🏁
• end — the address where the fill stops, the finish line fr fr 🏁

🦋 DESCRIPTION 🦋

So what it does: it goes looking for numa_meminfo memblks and extends them so they cover the physical address range from start to end. That's the whole vibe — find the memblks, stretch them out, cover the range. No cap 💫

⭐ RETURN ⭐

• 0 — success, we ate and left no crumbs 👑
• NUMA_NO_MEMBLK — no memblks exist in the address range start-end, tragic honestly 😭
