STRUCT NILFS_PERIOD(9)

👑 struct nilfs_period — it's a whole checkpoint-number era, bestie

okay so this is a page from the Kernel API Manual, and it's about struct nilfs_period — literally just a period of checkpoint numbers. That's the vibe. It's giving "start here, stop there, don't @ me." 💅

---

✨ NAME ✨

struct nilfs_period — a period of checkpoint numbers 🎀

---

🌸 SYNOPSIS 🌸

struct nilfs_period {
    __u64 p_start;
    __u64 p_end;
 };

---

🦋 Members 🦋

okay bestie, there are exactly two members and they are a matched set, no cap:

• p_start — the start checkpoint number, and it's inclusive 💖 (so like, this one counts, she's invited to the party)
• p_end — the end checkpoint number, and it's exclusive ✨ (this one does not count, she's outside the velvet rope, sorry not sorry)

so the range is lowkey half-open: p_start is in, p_end is out. periodt. 🫶
