STRUCT FAUX_DEVICE_OPS(9)

✨ struct faux_device_ops(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a tiny little struct from <pink>struct faux_device_ops(9)</pink> land and honestly? it's giving "small but mighty." let's get into it 🫶

---

🌸 NAME 🌸

struct faux_device_ops — literally just a set of callbacks for a struct faux_device 💅 that's it, that's the whole gig

---

🎀 SYNOPSIS 🎀

struct faux_device_ops {
    int (*probe)(struct faux_device *faux_dev);
    void (*remove)(struct faux_device *faux_dev);
 };

look at her. two little function pointers. iconic behavior, no notes 🔥

---

🦋 Members 🦋

• probe — this one gets called when a faux device is probed by the driver core, and the timing matters, bestie: it happens before the device is fully bound to the internal faux bus code. so if your probe slays, return 0. if it does not slay, return a negative error number to stop the probe sequence from succeeding. no pressure or anything 😭
• remove — called when a faux device is removed from the system. that's the whole vibe check. bye bestie 👋

---

🌈 Description 🌈

okay so here's the tea: both probe and remove are optional. like, genuinely optional, not fake-optional. if you don't need one of them, just set it to NULL and keep it moving 💜

fr fr, NULL is a valid choice here. don't overthink it. 🍓
