qla4xxx_pre..._port_reinit(9)

💅 qla4xxx_prevent_other_port_reinit(9) 💅

okay so this is a page straight out of the Kernel API Manual, and tbh it's a short one — but it's a cutie and it matters, so bestie, let's get into it 🫶

---

✨ NAME ✨

qla4xxx_prevent_other_port_reinit — prevent other port from re-initialize 🌸

like, the whole job is literally in the name, no cap.

---

🎀 SYNOPSIS 🎀

void qla4xxx_prevent_other_port_reinit (struct scsi_qla_host *ha );

it returns void (so, nothing back, she's a doer not a talker 💅) and takes exactly one thing.

---

🦋 ARGUMENTS 🦋

• ha — pointer to adapter structure ✨ (the adapter in question, she's the main character here)

---

🔥 DESCRIPTION 🔥

okay so picture this: the driver is getting removed from one ISP-4xxx port, right? This function goes and marks the other ISP-4xxx port so that port knows the driver is being removed. That's it, that's the whole vibe check ✅

the point is that the other port will not re-initialize while the ha is still in the process of being removed — whether that removal is happening because of a driver unload or an hba hotplug 🙈

it's giving "hey bestie, don't try to come back right now, we're literally in the middle of packing up" 😭 and honestly? iconic. someone had to say it.

ngl this is one of those tiny helper functions that eats 💀 if you skip it, the other port gets all eager and tries to re-init mid-teardown. do not skip it.
