nilfs_log_write_required(9)

💅 nilfs_log_write_required(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a little function from the nilfs2 world and honestly? she's the vibe check before any log writing happens 🎀

---

✨ NAME ✨

nilfs_log_write_required — literally just determines whether log writing is required 🫶 like, do we need to write logs or not, that's the whole gig

---

🌸 SYNOPSIS 🌸

bool nilfs_log_write_required (struct nilfs_sc_info *sci, int *modep);

---

🦋 ARGUMENTS 🦋

• sci — a nilfs_sc_info struct, she's the main character of this call ngl 💜
• modep — the location where the log writing mode gets stored 📍 like, here's where the mode goes if we're doing the thing

---

⭐ RETURN ⭐

Returns true if log writing is required, and false otherwise — no cap, that's the whole return situation 😭

And important: if log writing is required, the mode gets stored in the location pointed to by modep 👑 so that pointer is doing real work, don't sleep on her
