💅 lease_none_upgrade(9) — the kernel API glow-up you didn't know you needed

okay so bestie, welcome to lease_none_upgrade, a page straight out of the Kernel API Manual ✨ and honestly? it's giving "tiny function, big responsibilities." no cap.

---

🌸 NAME 🌸

lease_none_upgrade — the function that upgrades the lease state from none. like going from "i have zero plans tonight" to "actually i'm booked and busy" 💅

---

🦋 SYNOPSIS 🦋

int lease_none_upgrade (struct oplock_info *opinfo , __le32 new_state );

yes that's the whole thing. short, sweet, and absolutely doing the most in the background 🎀

---

🧚 ARGUMENTS 🧚

• opinfo — the current lease info. your main character struct, the one holding all the lore 👑
• new_state — the new lease state. the glow-up destination, type __le32 and all 💖

---

⭐ RETURN ⭐

• 0 — slay, it worked, success ✨
• otherwise -EINVAL — nope, invalid, we are not doing that today 😭

mwah 💜 that's the page! brought to you by the fine folks over at ./fs/smb/server, dated October 2026, and yes the version is giving future-tech main character energy. stay hydrated, upgrade those lease states responsibly, and remember: 0 on success, otherwise -EINVAL. periodt. 💅✨
