zfcp_erp_port_shutdown(9)

💅 zfcp_erp_port_shutdown 💅

Okay bestie, so this one lives in the Kernel API Manual, and it's literally the "shut it down" button for a port. No cap, that's the whole vibe. Let me walk you through it 🫶

---

✨ NAME ✨

zfcp_erp_port_shutdown — Shutdown port 🔌💀

---

🦋 SYNOPSIS 🦋

void zfcp_erp_port_shutdown (struct zfcp_port *port , int clear , char
*dbftag );

So she takes three things and returns nothing (void, she's giving low-commitment icon energy), and then she just… goes and shuts that port down. Periodt.

---

🌸 ARGUMENTS 🌸

• port — the port you're shutting down 💅 like, this is the port, the main character of this call.
• clear — status flags to clear 🧹 the little bits of state we're wiping on the way out.
• dbftag — tag for the debug trace event 🎀 so when you're snooping through traces later you can be like "oh that's mine, iykyk".

Fr fr, if you're shutting down one thing, you're probably about to shut down, reopen, or status-toggle something adjacent. It's giving "whole friend group coordinates the fit" 💀🌈
