set_smb2_rsp_status(9)

✨ set_smb2_rsp_status(9) ✨

okay so bestie, welcome to the kernel API manual page for set_smb2_rsp_status — it's a whole vibe, it lives in the ksmbd/smb server corner of the kernel, and it's literally one job: slapping an error response code onto an smb2 header. that's it. that's the whole girl. 💅

---

🌸 NAME 🌸

set_smb2_rsp_status — set error response code on smb2 header

---

🎀 SYNOPSIS 🎀

void set_smb2_rsp_status (struct ksmbd_work *work , __le32 err );

no cap, that's the entire signature. void return, two args, in and out. she's efficient. 👑

---

💖 ARGUMENTS 💖

• work — the smb work that's carrying the response buffer. think of it as the group chat thread where the reply is actually gonna get posted. 🫶
• err — the error response code. the message you're dropping in that thread. __le32, so little-endian, bestie, don't forget. 🧚

quick reminder bestie: err is __le32, so if you're hand-rolling that value, endianness is not a suggestion. 💀

okay that's the page!! mwah 💋 tiny little sign-off for the record: this one lives under ./fs/smb/server, dated October 2026, and the page itself is set_smb2_rsp_status(9) — she said "i'm the main character and i'm in the manual." periodt. 💜🌸✨
