nilfs_segctor_thread(9)

✨ nilfs_segctor_thread ✨

okay so bestie, welcome to the Kernel API Manual entry for nilfs_segctor_thread — this is the one that keeps the log writer thread alive and vibing 🫶

---

🌸 NAME 🌸

nilfs_segctor_thread — main loop of the log writer thread 💅

---

⭐ SYNOPSIS ⭐

int nilfs_segctor_thread (void *arg );

---

🎀 ARGUMENTS 🎀

• arg — a pointer to a struct nilfs_sc_info. that's it, that's the whole argument, she's lowkey simple like that 💖

---

🦋 DESCRIPTION 🦋

okay so nilfs_segctor_thread is the main loop function of the log writer kernel thread, and honestly she's the main character of this whole operation 👑

here's her whole thing: she checks whether log writing is actually necessary, and if it is — slay — she does the log write in the background. and if it's not necessary? she just waits. no cap, that's the vibe check 🌈

she's also the one who decides the background writeback of the superblock, so yeah, she's kind of a big deal ✨

---

💜 RETURN 💜

Always 0. every single time. iconic consistency, we love to see it 🎀

💀 reminder bestie: arg is a void * pointing at a struct nilfs_sc_info — don't go passing her anything else, okay? 🙈
