💅 mas_prealloc_calc(9) — the Kernel API Manual glow-up ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about mas_prealloc_calc — yes the manual name is baked in, we're not copying the header line, that's just where we live now 🫶

the squad. the whole group chat. all of them live in the kernel file ./lib/maple_tree.c, and here's the full roster, no one left behind (i would NEVER) 💖
