is_smb2_rsp(9)

✨ NAME ✨

okay so welcome to is_smb2_rsp(9) bestie — this is the section 9 kernel API page for is_smb2_rsp, and it literally just answers "is it smb2 response" 💅 like that's the whole job and honestly? iconic.

---

🌸 SYNOPSIS 🌸

bool is_smb2_rsp (struct ksmbd_work *work );

that's it. that's the function. returns a bool, takes one pointer, ate and left no crumbs 🎀

---

🦋 ARGUMENTS 🦋

• work — the smb work struct that's carrying the smb response buffer. that's the vibe check target, the thing you're asking the question about 🫶

---

🌈 RETURN 🌈

• true if it's an smb2 response 💖
• otherwise false 💀

no cap, it's that simple. no exit codes, no signals, no env vars, no hidden lore — just yes or no, queen 👑

lowkey a whole friend group of smb2 helpers and you're just the one asking "hey is this one of ours" at the door 🙈

and that's the whole page bestie, mwah 💋 this lil cutie lives in ./fs/smb/server and the version stamp on it is October 2026, so like… future-era kernel lore, we love to see it ⭐🦋💜
