smb2_set_ea(9)

💅 smb2_set_ea(9) — the kernel API manual, bestie edition ✨

okay so real talk, this page lives in section 9 of the Kernel API Manual and it's all about one little function that does A Big Job. buckle up 🎀

---

🌸 NAME 🌸

smb2_set_ea — the handler for setting extended attributes using the set info command. that's it, that's the whole vibe. it sets EAs. it's giving "quietly essential" tbh 🦋

---

✨ SYNOPSIS ✨

int smb2_set_ea (struct smb2_ea_info *eabuf , unsigned int buf_len ,
       const struct path *path , bool get_write );

like, look at her. four params, returns an int. no cap, she's iconic 👑

---

💖 ARGUMENTS 💖

• eabuf — the set info command buffer. this is the actual payload, the main character of the whole operation 🫶
• buf_len — the length of the set info command buffer. yes bestie, we need to know how much buffer we're buffering 📏
• path — the dentry path for get ea. it's literally the path we're pointing at 🌈
• get_write — get write access to a mount. so like, do we need write perms? this bool says yes or no, and honestly, it's serving gatekeeper 💅

---

🎀 RETURN 🎀

0 on success, otherwise error. that's the whole story — zero means slay, anything else means something went sideways 😭

🔥 SEE ALSO 🔥

so many siblings, she's got a whole family tree, and ngl the list is LONG but we're not skipping a single one because every single one of them matters 🧚

lowkey reminder bestie: that file path is ./fs/smb/server/smb2pdu.c and it's where all this lives. write it down, put it in your notes app, whatever, just don't lose it 🙈

and that's the page!! shipped straight from ./fs/smb/server, dated October 2026, and yes, it's still smb2_set_ea(9) at the bottom because she's consistent like that 💖⭐🎀
