STRUCT QUEUE_ENTRY(9)

💅 struct queue_entry(9) — like, the whole kernel API manual, but make it make sense 🎀

okay bestie, so this is struct queue_entry(9) from the Kernel API Manual, and honestly? it's giving "small struct, big responsibilities." it's a struct, it lives in the kernel, and it's literally one entry inside a &struct data_queue. slay. let's get into it 💖

---

✨ NAME ✨

struct queue_entry — the entry that lives inside the &struct data_queue. that's it, that's the vibe. main character energy in struct form 👑

---

🌸 SYNOPSIS 🌸

here's the whole thing, verbatim, no cap — don't touch the syntax, she's perfect as she is:

struct queue_entry {
    unsigned long flags;
    unsigned long last_action;
    struct data_queue *queue;
    struct sk_buff *skb;
    unsigned int entry_idx;
    void *priv_data;
 };

look at those fields. six of them. each one doing its little job 🫶

---

🦋 Members 🦋

okay so let's go field by field, because each one is a whole personality:

• flags — the entry flags. for the deets, go look at enum queue_entry_flags. that's where the flag lore lives 🚩
• last_action — the timestamp of the last change. literally "when did something last happen to me" as a field. relatable 😭
• queue — the data queue (struct data_queue) that this entry belongs to. it's the entry's home base, its chosen family 🏠
• skb — the buffer that's currently being transmitted (if this is a TX queue), or the one used to directly receive data in (if it's an RX queue). so it's the buffer, and which job it's doing depends on the queue type. dual threat, honestly ✨
• entry_idx — the entry index number. yes it's just a number. no it's not boring. it's the number 🔢
• priv_data — private data that belongs to this queue entry. heads up: the pointer points to data that's specific to a particular driver and queue type. so like, it's private-private. iykyk 🙈
