gen_pool_create(9)

📦 version 7.3.1, in nixpkgs unstable

💖 gen_pool_create(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the gen_pool_create(9) page and it's literally about making a brand-new special memory pool. buckle up, it's short but it's iconic ✨

🌸 SYNOPSIS 🌸

struct gen_pool * gen_pool_create (int min_alloc_order , int nid );

that's the whole signature, no cap — it hands you back a struct gen_pool * and it takes exactly two ints. slay 🫶

🎀 ARGUMENTS 🎀

  • min_alloc_order — the log base 2 of the number of bytes that each bitmap bit represents. yes, log base 2, like the exponent vibe — do the math, don't @ me 💅
  • nid — the node id of the node your pool structure should be allocated on… or -1 if you're not about that node life 🙈

🦋 DESCRIPTION 🦋

okay so here's the tea: this creates a new special memory pool. and what's a special memory pool for, you ask? it manages special purpose memory — aka memory that is not managed by the regular kmalloc/kfree interface. so it's giving main character memory that kmalloc literally cannot touch. periodt 💀✨

like, that's the entire friend group and they all ate 💅🌈

ngl there's not a ton of drama on this page — no warnings, no bugs section, just a clean little constructor. enjoy it while it lasts, bestie 🍓
