init_smk_fs(9)

🦋 init_smk_fs 💅

okay so bestie, this one's a kernel API manual page — init_smk_fs(9) — and it's literally the glow-up moment where smackfs gets its superblock. no cap, it's short but it matters. ✨

---

🌸 NAME 🌸

init_smk_fs — get the smackfs superblock 🎀

---

🫶 SYNOPSIS 🫶

int init_smk_fs (void );

---

💜 ARGUMENTS 💜

• void — no arguments, bestie. it takes literally nothing. iconique, honestly. 💅

---

🔥 DESCRIPTION 🔥

so the whole entire job here is: register the smackfs. that's it, that's the vibe. ✨

like, do not register smackfs if Smack wasn't enabled on boot. 🙈 we can't just tuck this method normally under the smack_init code path, because the security subsystem gets initialized before the vfs caches. it's giving scheduling conflict, and not the cute kind. 😭

it returns true if we were not chosen on boot, or if we were chosen and the filesystem registration succeeded. either way you're winning, periodt. 👑
