smb2_read(9)

🌸 smb2_read(9) 🌸

okay so this is a page straight out of the Kernel API Manual, section 9, and it's giving "the girlies in ./fs/smb/server wrote this in October 2026 and it absolutely ate." it's short, it's sweet, and it's about one (1) function. let's go 💅

---

✨ NAME ✨

smb2_read — the handler for an smb2 read from a file. that's it, that's the whole job. she shows up when somebody wants bytes out of a file over smb2 and she handles it. iconic behavior honestly 🫶

---

💖 SYNOPSIS 💖

int smb2_read (struct ksmbd_work *work );

one (1) argument, one (1) int coming back at you. no cap.

---

🎀 ARGUMENTS 🎀

• work — an smb work that's carrying the read command buffer. like, the whole request lives in there, she just gets handed the bag and does her thing 💼✨

---

⭐ RETURN ⭐

0 on success, otherwise error. that's the whole vibe check:

• 0 → we ate, no notes 🔥
• anything else → error, and yes that's literally all the docs say, so don't come for me 😭

and that's the page!! sign-off time: this little beauty lives down in ./fs/smb/server, the date on her birth certificate says October 2026, and the footer just repeats smb2_read(9) back at you like a mirror selfie because she knows she's that girl 🪞💅 bye bestie, happy reading 🌈✨
