mpi3mr_repor...tdev_to_host(9)

🦋 mpi3mr_report_tgtdev_to_host — Kernel API Manual, section 9 🦋

okay so bestie, we're in the Kernel API Manual and this page is literally called mpi3mr_report_tgtdev_to_host(9). yes the header slays, yes it's giving "long function name energy," and no we are not scared of it 💅

---

✨ NAME ✨

mpi3mr_report_tgtdev_to_host — expose the device to the upper layers 👑

---

✨ SYNOPSIS ✨

int mpi3mr_report_tgtdev_to_host (struct mpi3mr_ioc *mrioc , u16
perst_id );

like… it takes two things and returns an int. that's it. that's the whole vibe check 🫶

---

✨ ARGUMENTS ✨

• mrioc — your adapter instance reference. the whole controller, the main character. 🎀
• perst_id — the persistent ID of the device. yes, persistent, like that one friend who never leaves the group chat. 🌸

---

✨ DESCRIPTION ✨

so what does it actually do? it checks whether the device can be exposed to upper layers, and if it is not already exposed, then it exposes the device to upper layers by calling scsi_scan_target. 🦋

that's the whole thing. it's a vibe-check-then-do-the-thing function. no cap, that's the entire flow ✨

ngl this one's short but it's important — it's literally the "hey upper layers, look at this device" moment 🔥

---

✨ RETURN ✨

• 0 — on success 💖 slay.
• non zero — on failure 😭 and yes, it's just "non zero," we don't get to know which. mysterious. iconic. 💀

💜 that's the whole page. drink water, read your man pages, and remember: 0 means slay and non-zero means 😭

okay bye bestie — this one came from ./drivers/scsi/mpi3mr, dated October 2026, and it was served to you fresh as mpi3mr_repor...tdev_to_host(9) 🎀✨🫶
