lpfc_fcp_cpu_map_store(9)

💖 NAME 💖

okay so bestie, welcome to the lpfc_fcp_cpu_map_store(9) page from the Kernel API Manual! the whole NAME vibe is literally: lpfc_fcp_cpu_map_store — Change CPU affinity of driver vectors. that's it, that's the name, and it ate. 💅

---

✨ SYNOPSIS ✨

the signature is right here, untouched, no crumbs:

ssize_t lpfc_fcp_cpu_map_store (struct device *dev , struct
device_attribute *attr , const char *buf , size_t count );

---

🎀 ARGUMENTS 🎀

• dev — class device that is converted into a Scsi_host.
• attr — device attribute, not used. nope, not even a little.
• buf — one or more lpfc_polling_flags values.
• count — not used.

---

🔥 RETURN 🔥

• -EINVAL — Not implemented yet.

heads up bestie: the return section is literally just that one line, so don't go looking for a whole novel of return codes. 😭

🌈 SEE ALSO 🌈

okay this SEE ALSO list is not a drill — it's the entire group chat, and every single reference is invited. no skips, no crumbs, no cap. 🫶
