STRUCT FUSE_IQUEUE_OPS(9)

💅 struct fuse_iqueue_ops(9)

okay bestie, welcome to the Kernel API Manual entry for struct fuse_iqueue_ops(9) — yes it's a kernel thing, no you don't have to be scared, I got you 🫶

---

✨ NAME ✨

struct fuse_iqueue_ops — literally just the input queue callbacks 💖 that's it, that's the whole vibe.

---

🌸 SYNOPSIS 🌸

struct fuse_iqueue_ops {
    void (*send_forget)(struct fuse_iqueue *fiq, struct fuse_forget_link
*link);
    void (*send_interrupt)(struct fuse_iqueue *fiq, struct fuse_req
*req);
    void (*send_req)(struct fuse_iqueue *fiq, struct fuse_req *req);
    void (*release)(struct fuse_iqueue *fiq);
 };

no cap, that's the whole struct. four little function pointers and they're all doing the most 🙈

---

🎀 Members 🎀

okay so let's meet the cast, main character energy only:

• send_forget — sends one forget. just one. iconic minimalism ✨
• send_interrupt — sends the interrupt for a request 🔥
• send_req — sends one request, classic 💅
• release — the cleanup crew 🧹 runs when the fuse_iqueue is destroyed. we love a tidy queen.

🦋 Description 🦋

so here's the tea ☕ — input queue signalling is device-specific. like, every device type has its own way of doing things and that's valid, it's giving individuality.

for example, the /dev/fuse file uses fiq->waitq and fasync to wake processes that are waiting on queue readiness 😴➡️😳 yeah, the wakeup moment.

basically these callbacks are the plug-and-play moment: they let other device types respond to input queue activity too 🌈 lowkey the whole point of the struct. iykyk.
