smk_write_load_self(9)

💅 smk_write_load_self — like, the whole kernel API manual situation ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is smk_write_load_self(9). no cap, she's the write() handler for /smack/load-self, and she's lowkey iconic. let's get into it 🎀

---

🌸 NAME 🌸

smk_write_load_self — literally the write() for /smack/load-self. that's it, that's the vibe. periodt.

---

✨ SYNOPSIS ✨

ssize_t smk_write_load_self (struct file *file , const char __user *buf
, size_t count , loff_t *ppos );

look at her go 😭 the signature is giving main character energy fr fr.

🦋 ARGUMENTS 🦋

so here's who's showing up to the function party 💖

• file — a file pointer, and ngl she's not actually used. she's just there. invited but not participating, we love a supportive queen 🙈
• buf — this is where the data comes from, like the source of truth, the vibe check origin point ✨
• count — how many bytes got sent. the byte count, the receipts, the numbers 💅
• ppos — where to start, and bestie, it must be 0. no exceptions, that's the rule 👑
