mpi3mr_update_mr_sas_port(9)

💅 mpi3mr_update_mr_sas_port(9) — a Kernel API Manual moment

Okay bestie, so this is a page from the Kernel API Manual, and the function is mpi3mr_update_mr_sas_port — say that five times fast, I dare you 😭

🌸 NAME 🌸

mpi3mr_update_mr_sas_port — literally just here to update sas port objects during reset, no biggie ✨

---

🦋 SYNOPSIS 🦋

void mpi3mr_update_mr_sas_port (struct mpi3mr_ioc *mrioc , struct
host_port *h_port , struct mpi3mr_sas_port *mr_sas_port );

No return value, no drama. It's giving "I do my job and I leave" energy 👑

---

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference 💖 (the whole adapter's lil handle, okay?)
• h_port — host_port object 🌸 (that's literally what it is, bestie)
• mr_sas_port — sas_port objects which needs to be updated ⭐ (the ones getting the glow-up)

---

✨ DESCRIPTION ✨

So what does it actually do? Two things, and I'm obsessed:

It updates the port ID of the sas port object 🔥 — like a little name tag refresh, slay.

And it fixes up the phys list: it adds the phys if new phys got added to the current sas port, and removes the phys if some phys are moved out of the current sas port 💅. In-and-out, like a group chat with very strict membership rules. Phys join, phys leave, the sas port keeps it cute and accurate 🫶

---

💜 RETURN 💜

Nothing. Zero. Nada. void era 💀 — it does the work and doesn't even want a return value. Main character energy fr fr.

Heads up bestie: everything above is exactly what the page says — I'm not adding extra lore, no cap. If it's not on the page, it's not in the group chat 💅

And that's the whole vibe check! This cutie lives in ./drivers/scsi/mpi3mr and the page is dated October 2026 ⭐ — go forth and update those sas ports, queen 👑💖
