📦 version 7.3.1, in nixpkgs unstable

💅 nvme_fc_unregister_localport(9) — from the Kernel API Manual, bestie

Okay so picture this: you're an LLDD (a low-level device driver, iykyk) and you've already registered a NVME host FC port. Now you gotta take it back. Undo. Ctrl+Z but for kernel ports. That's this function. It's the transport entry point an LLDD calls to deregister/remove a previously registered NVME host FC port. Cleanup era ✨

🎀 NAME 🎀

nvme_fc_unregister_localport — the transport entry point that an LLDD calls to deregister/remove a previously registered NVME host FC port. Basically the "we're so done here" button 🫶

✨ SYNOPSIS ✨

int nvme_fc_unregister_localport (struct nvme_fc_local_port *portptr );

🌸 ARGUMENTS 🌸

  • portptr — pointer to the (registered) local port that is to be deregistered. Yes bestie, it has to be the registered one — that's the whole vibe 💅

🔥 RETURN 🔥

It gives you back a completion status, periodt.

  • It must be 0 upon success — zero, iconic, no notes 👑
  • A negative errno upon failure (ex: -ENXIO) — so like, if it's negative, something went sideways 😭
Fr fr, the "must be 0 upon success" is not a suggestion, it's the rule. Don't be out here returning chaos.

Cute little sign-off: this one lives in ./drivers/nvme/host, and it's dated October 2026. Go deregister responsibly, bestie 🎀✨
