💅 ksmbd_vfs_write(9) — like, the kernel API manual bestie 💅

okay so this is the page for ksmbd_vfs_write, straight out of the Kernel API Manual — yes, that's the manual name, we're being ✨official✨ today. It's the vfs helper for smb file write, and honestly? iconic behaviour. Let's get into it 🫶

🌸 NAME 🌸

ksmbd_vfs_write — the vfs helper for smb file write. that's it, that's the vibe. no cap, it does exactly what it says 🎀

---

✨ SYNOPSIS ✨

int ksmbd_vfs_write (struct ksmbd_work *work , struct ksmbd_file *fp ,
char *buf , size_t count , loff_t *pos , bool sync , ssize_t *written );

look at her. seven whole arguments. main character energy fr fr 👑

---

🦋 ARGUMENTS 🦋

• work — work
• fp — the ksmbd file pointer, i.e. the file we're obsessed with rn
• buf — buf containing data for writing. the payload. the moment. 💖
• count — read byte count (yes bestie, "read" — that's literally what the page says, I don't make the rules 💀)
• pos — file pos, the little address of where we're at in the file
• sync — fsync after write, so like… should we commit to it commit to it? 🌈
• written — number of bytes written, the receipts, the proof, the slay 📝

---

⭐ RETURN ⭐

0 on success, otherwise error. that's the whole deal. zero means we ate, anything else means something went sideways 😭
