alloc_nilfs(9)

💫 alloc_nilfs — from the Kernel API Manual, section 9, bestie 💫

okay so we're in the kernel API manual, section 9, and today's main character is alloc_nilfs. it does exactly one thing and it does it iconically: it allocates a nilfs object. that's it, that's the whole vibe check ✨

---

🌸 NAME 🌸

alloc_nilfs — allocate a nilfs object. literally what it says on the tin, no notes 💅

---

🎀 SYNOPSIS 🎀

struct the_nilfs * alloc_nilfs (struct super_block *sb );

look at that signature. so clean. so crisp. yes bestie, that space before the semicolon is supposed to be there, i don't make the rules 🫶

---

🦋 ARGUMENTS 🦋

• sb — super block instance. that's the super block you're handing over so the nilfs object can get allocated. the one little friend you gotta bring to the function party 💖

---

🔥 RETURN 🔥

on success? you get a pointer to the allocated nilfs object, heck yes 👑

on failure? it returns NULL. which, ngl, is the saddest possible outcome. check for it, bestie, always check 😭
