STRUCT WP_WALK(9)

💅 struct wp_walk(9) — Kernel API Manual 💅

okay so bestie, welcome to the struct wp_walk(9) page — the manual name is literally folded in right here at the top, with love 💖. This is the private struct for pagetable walk callbacks, and it's giving "small struct, important job" energy.

✨ NAME ✨

struct wp_walk — private struct for pagetable walk callbacks. That's it, that's the name, no cap.

🌸 SYNOPSIS 🌸

       struct wp_walk {
           struct mmu_notifier_range range;
           unsigned long tlbflush_start;
           unsigned long tlbflush_end;
           unsigned long total;
        };

🎀 Members 🎀

• range — range for mmu notifiers. The mmu notifier range, exactly as advertised.
• tlbflush_start — address of first modified pte. First modified pte, periodt.
• tlbflush_end — address of last modified pte + 1. Not the last pte itself — plus one, iykyk.
• total — total number of modified ptes. The whole count, nothing but the count 💅.
