STRUCT SRPT_PORT_ID(9)

✨ struct srpt_port_id(9) ✨

okay bestie, we're diving into the Kernel API Manual for struct srpt_port_id and honestly? it's giving "small but mighty" 💅 this is the LIO RDMA port info situation, and we're gonna break it down so you can slay your kernel understanding fr fr.

🎀 NAME 🎀

struct srpt_port_id — literally just the LIO RDMA port information, no cap. it's the struct that holds all the deets about a single (port, name) pair. iconic behavior tbh.

---

🌸 SYNOPSIS 🌸

okay so here's the actual structure, look at her:

struct srpt_port_id {
    struct mutex            mutex;
    struct list_head        tpg_list;
    struct se_wwn           wwn;
    char name[64];
 };

that's it. that's the whole vibe. four members, each one doing its absolute thing. periodt.

💖 Members 💖

let's meet the cast, bestie — every single one matters:

• mutex — this is the bodyguard 🫶 it protects tpg_list changes. like, don't touch the list without going through the mutex first, that's the rule.
• tpg_list — all the TPGs chillin' here, associated with the RDMA port name. this is the main character list ngl.
• wwn — the WWN associated with the RDMA port name. world wide name energy, we love to see it ✨
• name — the ASCII representation of the port name. it's a char[64] so it can hold a whole 64 characters of pure port-name identity 💅

---

🦋 Description 🦋

okay so here's the tea: multiple sysfs directories can be associated with a single RDMA port. wild, right? 😭 and this data structure? it represents a single (port, name) pair. so like, one struct = one pairing, and that's the whole point. it's giving "organized chaos" and honestly we're obsessed.
