💅 nvmet_fc_unregister_targetport(9) — the Kernel API Manual page, bestie edition 🎀

okay so real talk, this one lives in the Kernel API Manual, and it's the lil function that says "bye bestie 👋" to a target port. welcome to the group chat.

✨ NAME ✨

nvmet_fc_unregister_targetport — it's the transport entry point that an LLDD calls to deregister/remove a local NVME subsystem FC port that was previously registered. basically: the un-register. the farewell tour. the "we are so done here" moment 🫶

---

✨ SYNOPSIS ✨

int nvmet_fc_unregister_targetport (struct nvmet_fc_target_port
*target_port );

like, it returns an int, it takes one thing, it's giving very low-drama signature ngl 💅

---

✨ ARGUMENTS ✨

• target_port — a pointer to the (registered) target port that is to be deregistered. yes, the registered one — that's the whole vibe. this is the port you're about to send off into the sunset 🌅

---

✨ RETURN ✨

it hands back a completion status. the rules are:

• must be 0 upon success ✨ (slay, it worked)
• a negative errno upon failure 😭 — for example -ENXIO

fr fr, check that return value. 0 = iconic, negative = go read your errno and have a little think.
