lwmi_om_fan...llect_cd_fan(9)

💅 lwmi_om_fan_info_collect_cd_fan — the girlies of section 9

okay so real quick, bestie: this whole page lives in the Kernel API Manual, section 9 — that's the kernel-functions girlies, not the shell-command ones 💫 and the page name got lopped off real cute as lwmi_om_fan...llect_cd_fan(9) because apparently even man page headers have a character limit 🙈 don't worry about it, we know who she is.

✨ NAME ✨

lwmi_om_fan_info_collect_cd_fan — she collects fan info from capdata fan 🌀💖 that's it, that's the whole job, and she does it flawlessly.

---

🎀 SYNOPSIS 🎀

void lwmi_om_fan_info_collect_cd_fan (struct device *dev , struct
cd_list *cd_fan_list );

no return value, no drama, just vibes and side effects 🫶 (it's void, so like… she gives nothing back, but she did the work, iykyk).

---

🌸 ARGUMENTS 🌸

• dev — Pointer to the lenovo-wmi-other device 💻✨ this is the main character, the device she's pulling from.
• cd_fan_list — Pointer to the capdata fan list 📋🦋 this is where the collected fan info ends up. the little list bestie gets filled up.

both of these are pointers, so please don't hand her a NULL and expect a slay — the page does not promise anything about that, and I'm not about to make stuff up 💀

okay that's the page!! no cap, that was all of it 🌈⭐ this icon dropped way back in October 2026, lives in ./drivers/platform/x86/lenovo, and the header/footer both say lwmi_om_fan...llect_cd_fan(9) because truncation is her aesthetic 😭💀 bye bestie, go collect those fans 🦋🌸
