smb2_lock(9)

💅 smb2_lock — like, the whole vibe check

Okay so bestie, welcome to smb2_lock(9) from the Kernel API Manual (yes, section 9, the fancy section) 🎀. This is the handler for the smb2 file lock command — the little icon that goes "this file is MINE, do not touch" 🔒✨. It's giving gatekeeper energy and honestly? Iconic.

---

✨ SYNOPSIS ✨

int smb2_lock (struct ksmbd_work *work );

That's it. That's the whole signature. Short, sweet, main character energy 🫶.

---

🌸 ARGUMENTS 🌸

• work — a smb work, and it's literally carrying the lock command buffer around like it's holding your iced coffee 🧋. That's the thing this function chews on.

---

⭐ RETURN ⭐

• 0 on success — slay 💖
• otherwise, an error 😭 — not slay, but it's honest about it

ngl bestie, 0 means you ate, anything else means the error path is doing its thing. That's the entire contract, no cap 💀

Okay byeee, this page came from ./fs/smb/server, dated October 2026, and it's filed under smb2_lock(9) — go lock some files (responsibly) 💜✨
