zfcp_port_enqueue(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zfcp_port_enqueue(9) — like, the Kernel API Manual entry you didn't know you needed 🎀

okay bestie, so this is from the Kernel API Manual, section 9, and the function is literally called zfcp_port_enqueue ✨ — let's get into it, no cap.

🌸 NAME 🌸

zfcp_port_enqueue — enqueue a port to the port list of an adapter. that's it. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

struct zfcp_port * zfcp_port_enqueue (struct zfcp_adapter *adapter , u64
wwpn , u32 status , u32 d_id );

like just look at her. four args, one return, main character energy 👑

🧚 ARGUMENTS 🧚

  • adapter — the adapter where the remote port gets added. it's giving "hostess of the party" 🫶
  • wwpn — the WWPN of the remote port that's about to be enqueued. yes, you need it, don't skip it 🙈
  • status — the initial status for the port. first impressions, fr fr 💖
  • d_id — the destination id of the remote port to be enqueued. lowkey important, we'll get to why ⭐

💫 RETURN 💫

pointer to the enqueued port on success — and ERR_PTR on error 😭. so like, vibe check the return value before you go dereferencing, okay? 💀

🔥 DESCRIPTION 🔥

so what actually happens: all the port internal structures get set up, and the sysfs entry is generated ✨ — like she's moving in and putting up fairy lights, the whole place gets furnished 🎀

and d_id? that's the icon of this whole function. it's literally used to enqueue ports with a well known address, like the Directory Service for nameserver lookup 👑 iykyk — that's the special case and it slays 🌈

🌟 SEE ALSO 🌟

go read those too, bestie, they're all part of the same friend group 💜

ngl, keep the ERR_PTR case in your head at all times — a pointer that looks like a port but is actually an error is not the plot twist you want 😭 🍓
