💅 nfs41_discover_server_trunking — a.k.a. the "is this the same server or not" vibe check

okay so bestie, you're in the Kernel API Manual, section 9 (kernel routines, iykyk). Buckle up 🎀

---

✨ NAME ✨

nfs41_discover_server_trunking — Detect server IP address trunking (mv1) 🦋

Like, it figures out whether two things that look different are actually the same server. Main character detective energy, fr fr.

---

🌸 SYNOPSIS 🌸

int nfs41_discover_server_trunking (struct nfs_client *clp , struct nfs_client **result , const struct cred *cred );

---

🫶 ARGUMENTS 🫶

• clp — the nfs_client under test. She's the one being examined 👀
• result — OUT param: the found nfs_client, or clp. So like, a pointer gets planted here — either the one we discovered or the original we walked in with 💖
• cred — the credential to use for the trunking test. Gotta have your ID ready for the vibe check 🔥

---

👑 DESCRIPTION 👑

Returns NFS4_OK, a negative errno, or a negative NFS4ERR status — three possible outcomes, no in-between, periodt.

If NFS4_OK is returned, an nfs_client pointer is planted in "result". Yup, that's the whole deal. Slay 💅

---

⭐ NOTE ⭐

Lowkey important bestie: the returned client may not yet be marked ready. So don't go treating it like it's fully cooked, ngl 🙈
