init_nilfs(9)

💖 init_nilfs(9) — Kernel API Manual 💖

okay bestie, we're in the Kernel API Manual and this one is literally called init_nilfs. it is giving NILFS setup energy, and yes you're gonna understand it. periodt. ✨

🎀 NAME 🎀

init_nilfs — initialize a NILFS instance. no cap, that's the whole name section and it ate. 💫

✨ SYNOPSIS ✨

int init_nilfs (struct the_nilfs *nilfs , struct super_block *sb );

🦋 ARGUMENTS 🦋

• nilfs — the struct named the_nilfs. yes bestie, it's literally the_nilfs, iykyk. 🫶
• sb — super block. iconic, essential, we love her. 🌸

🌈 DESCRIPTION 🌈

okay so init_nilfs performs common initialization per block device (e.g. reading the super block, getting disk layout information, initializing shared fields in the_nilfs). it's lowkey the setup chapter of the NILFS story, and it's doing main character work. 🔥

💅 RETURN 💅

0 on success, or a negative error code on failure. that's the whole return vibe: zero means slay, negative means something went sideways. 😭
