STRUCT ZFCP_FC_WKA_PORT(9)

✨ NAME ✨

okay so this is struct zfcp_fc_wka_port — the representation of a well-known-address (WKA) FC port, bestie 💅. it's from the Kernel API Manual, and it's genuinely iconic for what it does. periodt.

🦋 SYNOPSIS 🦋

like, here's the whole vibe, literally character for character:

struct zfcp_fc_wka_port {
    struct zfcp_adapter     *adapter;
    wait_queue_head_t opened;
    wait_queue_head_t closed;
    enum zfcp_fc_wka_status status;
    atomic_t refcount;
    u32 d_id;
    u32 handle;
    struct mutex            mutex;
    struct delayed_work     work;
 };

ngl, that's the entire main character right there 👑

🎀 Members 🎀

every single field, no skips, no cap:

• adapter — a pointer to the adapter structure that this WKA port belongs to 🫶
• opened — the wait queue situation: you're waiting for the open command to complete
• closed — same energy but for the close command completing
• status — the current status of the WKA port, iykyk
• refcount — reference count whose whole job is keeping the port open for as long as it's in use 🔥
• d_id — the FC destination id, or the well-known-address itself
• handle — the FSF handle for the open WKA port
• mutex — mutex used during opening/closing state changes (protecting the vibes 💀)
• work — for delaying the closing of the WKA port 🌸
