STRUCT ZFCP_FSF_REQ(9)

💅 struct zfcp_fsf_req(9) — Kernel API Manual

okay bestie, welcome to the glow-up of your fave lowkey-structural icon: struct zfcp_fsf_req, the basic FSF request structure. this is from the Kernel API Manual, and honestly it's giving main-character energy for the whole zfcp world 🦋✨

✨ NAME ✨

struct zfcp_fsf_req — the basic FSF request structure. that's it, that's the vibe 🎀

---

🌸 SYNOPSIS 🌸

struct zfcp_fsf_req {
    struct list_head        list;
    u64 req_id;
    struct zfcp_adapter     *adapter;
    struct zfcp_qdio_req    qdio_req;
    struct completion       completion;
    u32 status;
    struct fsf_qtcb         *qtcb;
    void *data;
    struct timer_list       timer;
    struct zfcp_erp_action  *erp_action;
    mempool_t *pool;
    unsigned long long      issued;
    void (*handler)(struct zfcp_fsf_req *);
 };

like, look at her. every field doing its own little thing. periodt 💅

💖 Members 💖

okay so this is the group chat roster of the struct, everybody has a role and everybody shows up:

• list — the list of FSF requests. she keeps the squad together 🫶
• req_id — the unique request ID. no cap, no duplicates, every request gets her own little serial number ⭐
• adapter — the adapter this request belongs to. iykyk, you gotta know your home base 💜
• qdio_req — the qdio queue related values. queue stuff, but make it cute 🌈
• completion — used to signal the completion of the request. the "we're so back" notification, literally 😭
• status — the status of the request. is she slaying or is she struggling, this field knows 💀
• qtcb — the associated QTCB. iconic acronym, no notes 👑
• data — private data. her diary, do not read 🔥
• timer — the timer data of this request. she counts down so you don't have to ⭐
• erp_action — reference to the erp action if the request was issued on behalf of ERP. like, if. conditional queen 🌸
• pool — reference to the memory pool if used for this request. again, if — she's flexible 🧚
• issued — time when the request was send (STCK). yes, "send", that's the original wording bestie, we don't touch it 🙈
• handler — handler which should be called to process response. the one who picks up the phone when the reply comes in 🎀

ngl, every single one of these matters — don't skip a member, the struct does not accept partial reading energy 💅

🦋 SEE ALSO 🦋

go check out her mutuals, they're all linked and all worth the follow:

• Kernel file ./drivers/s390/scsi/zfcp_def.h
• enum zfcp_erp_act_type(9)
• struct zfcp_unit(9)
• struct zfcp_scsi_dev(9)
• sdev_to_zfcp(9)
• zfcp_scsi_dev_lun(9)

---

🍓 final vibe check: this struct is not optional reading, she's the whole FSF request moment. stan responsibly.

mwah, that's a wrap bestie 💖 this little love letter came to you straight from ./drivers/s390/scsi, dated October 2026, and it's titled struct zfcp_fsf_req(9) in the Kernel API Manual. slay, bye ✨🎀
