STRUCT KVM_PGTABLE_WALKER(9)

💅 struct kvm_pgtable_walker(9) — the Kernel API Manual, but make it make sense

okay so bestie, this is a page from the Kernel API Manual — the manual name is literally struct kvm_pgtable_walker(9) and yes we're gonna say it every time because it's iconic. Let's get into it. 🎀

---

✨ NAME ✨

struct kvm_pgtable_walker — the little hook you use to get all up in a page-table walk. like, you don't just watch the walk, you get to do stuff during it. main character energy fr fr. 👑

---

🦋 SYNOPSIS 🦋

struct kvm_pgtable_walker {
    const kvm_pgtable_visitor_fn_t          cb;
    void * const                            arg;
    const enum kvm_pgtable_walk_flags       flags;
 };

that's the whole struct. three fields. no notes. she's perfect. 💖

---

🌸 Members 🌸

• cb — the callback function that gets invoked during the walk. this is your moment, your solo, your time to shine ✨ — when the walker hits the right kind of entry, this bad boy gets called.
• arg — the argument you hand off to that callback function. void * const, so like… it's a pointer that stays a pointer. no take-backs. 🫶
• flags — a bitwise-OR of flags that tell you which entry types should trigger the callback function. so basically you pick and choose which entries get the callback, using OR'd flags. iykyk 💅

ngl these three are the entire struct, so there's literally nothing else hiding in here. no secret fourth member. stop looking. 🙈
