STRUCT DAMOS_WALK_CONTROL(9)

✨ struct damos_walk_control(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the Kernel API Manual, we're in the big leagues now 💅 — and it's literally all about struct damos_walk_control, which is the little control-freak struct that runs the show for damos_walk(). main character energy fr fr 👑

🌸 NAME 🌸

struct damos_walk_control — the thing that controls damos_walk(). that's it, that's the whole name, and she ate 🎀

🦋 SYNOPSIS 🦋

struct damos_walk_control {
    void (*walk_fn)(void *data, struct damon_ctx *ctx, struct
damon_target *t, struct damon_region *r, struct damos *s, unsigned long
sz_filter_passed);
    void *data;
 };

like… look at her. two members. no notes. 💖

👑 Members 👑

• walk_fn — the callback function, aka the girl who gets called back for each region. every single one. she shows up 💅
• data — the payload, the little bundle of stuff that gets passed along to the walk functions. think of it as the aux cord 🎧

🌈 Description 🌈

so basically — this struct is what controls damos_walk, which is the thing that requests a specific kdamond to invoke the given function on each region that's eligible to apply actions of that kdamond's schemes. yes, that sentence is a lot, i know, but it's the whole vibe.

if you want the full lore, bestie, go refer to damos_walk for more details. iykyk 🫶

ngl this one's short and sweet — but don't sleep on it, she's load-bearing ✨
