unmap_cmd_data(9)

💅 unmap_cmd_data — the kernel API manual, bestie edition ✨

okay so bestie, you're looking at unmap_cmd_data from the Kernel API Manual, and honestly? it's giving "cleanup era." 🧹

---

✨ NAME ✨

unmap_cmd_data — Unmap data pointed in srp_cmd based on the format 🎀

---

🦋 SYNOPSIS 🦋

void unmap_cmd_data (struct srp_cmd *cmd , struct srp_event_struct
*evt_struct , struct device *dev );

like... that's the whole signature. three args, zero drama. periodt. 💅

---

🌸 ARGUMENTS 🌸

• cmd — the srp_cmd whose additional_data member will be unmapped. yeah, that member. it's getting unmapped. iconic behavior honestly 🫶
• evt_struct — the event. just... the event. it's there, it's vibing, it's doing its thing ✨
• dev — the device for which the memory is mapped. so like, the memory is mapped for this device, and now we're un-mapping it. circle of life, lowkey 🌈

bestie heads up 🫶 — this page lives under ./drivers/scsi/ibmvscsi, and the docs are stamped October 2026. screenshot that date for the group chat, it's giving main character energy 👑

🌸 mwah, go unmap that data, you absolute icon 💜
