STRUCT DMA_FENCE_CB(9)

✨ struct dma_fence_cb(9) ✨

okay bestie so this is from the Kernel API Manual and it's literally the whole vibe of struct dma_fence_cb — a callback holder for dma_fence_add_callback() 🎀

---

🌸 NAME 🌸

struct dma_fence_cb — the callback for dma_fence_add_callback() 💅

---

🦋 SYNOPSIS 🦋

struct dma_fence_cb {
    struct list_head node;
    dma_fence_func_t func;
 };

---

🎀 Members 🎀

• node — this one is used by dma_fence_add_callback to append this struct to fence::cb_list 🫶
• func — the dma_fence_func_t to call ⭐

---

💖 Description 💖

so this struct gets initialized by dma_fence_add_callback, and if you want extra data passed along you do it by embedding dma_fence_cb in another struct ✨ like that's the whole move. main character energy fr fr 💅
