STRUCT TIMESTAMP_REG_FREE_NODE(9)

✨ NAME ✨

struct timestamp_reg_free_node — bestie, this struct literally holds the timestamp registration free objects node. That's the whole gig, no cap. 💖

🦋 SYNOPSIS 🦋

okay so here's the struct in all its glory, and yes, every field is exactly where it should be:

       struct timestamp_reg_free_node {
           struct list_head        free_objects_node;
           struct hl_cb            *cq_cb;
           struct hl_mmap_mem_buf  *buf;
           atomic_t in_use;
           u8 dynamic_alloc;
        };

slay. that's the shape of it. 🎀

🌸 MEMBERS 🌸

• free_objects_node — the node in the list free_obj_jobs, periodt. it's giving linked-list main character energy. 🔥
• cq_cb — pointer to the cq command buffer to be freed. lowkey important. 💅
• buf — pointer to the timestamp buffer to be freed. yes bestie, it's a buffer and it's gonna get freed. ✨
• in_use — indicates whether the node is still in use in the workqueue thread. this is the vibe check field. 👑
• dynamic_alloc — indicates whether the node was allocated dynamically in the interrupt handler. that's the tea. 🍓
