smk_write_load_self2(9)

💅 smk_write_load_self2 — the write() bestie for /smack/load-self2

okay so real talk, this is smk_write_load_self2(9) from the Kernel API Manual, and she's the function that handles everything you write into /smack/load-self2. yes bestie, that's literally the whole vibe. she takes your bytes and she does the thing. no cap.

✨ SYNOPSIS ✨

ssize_t smk_write_load_self2 (struct file *file , const char __user *buf
, size_t count , loff_t *ppos );

look at her. iconic signature. don't touch a single character of it 🫶

🎀 ARGUMENTS 🎀

• file — the file pointer, and honestly? she does not use it. not even a little. it's giving decoration. it's giving "invited to the party but stays in the corner." lowkey not actually used 💀
• buf — this is where the data comes from, bestie. the actual goods. the tea. source of truth for what you're writing.
• count — how many bytes got sent. the size of what you're handing over. do the math, love it.
• ppos — where to start, and ngl there's exactly one correct answer here: it must be 0. zero. that's it. that's the whole requirement. any other number and she's not entertaining it 🙈
