__smb_break_...levII_oplock(9)

💅 __smb_break_...levII_oplock(9) — like, the Kernel API Manual page, bestie ✨

okay so sit down, grab a strawberry 🍓, because we're talking about the __smb_break_...levII_oplock(9)</p> page from the Kernel API Manual and honestly it's giving very niche-but-iconic. iykyk 💅

✨ NAME ✨

__smb_break_all_levII_oplock — sends a level2 oplock break or a read lease break command, and the direction is server → client, no cap 🫶

Like literally that's the whole assignment: server tells the client "hey bestie, your lock situation needs to change."

---

🦋 SYNOPSIS 🦋

void __smb_break_all_levII_oplock (struct ksmbd_work *work , struct
ksmbd_file *fp , int is_trunc , bool send_interim , bool
send_oplock_break , bool sync_lease_break );

she takes six arguments and returns void, so no return value to obsess over 💀

---

🎀 ARGUMENTS 🎀

• work — the smb work. the main character of the function call, fr fr 👑
• fp — the ksmbd file pointer. like, which file are we even talking about? this one 💖
• is_trunc — truncate on open. yep, that's the flag 🩷
• send_interim — send interim response to the client. a little "hang on bestie, we're working on it" message ✨
• send_oplock_break — send oplock break notification to the client. the actual ✨drama✨ delivery 🔥
• sync_lease_break — send the lease break notification synchronously. no shortcuts, we wait, periodt 💅

ngl all six of these are bool except the first three, so mind your types — struct ksmbd_work *, struct ksmbd_file *, int, then three bools. copy the signature exactly, don't get creative 🙈
