bch_next_delay(9)

💅 bch_next_delay 💅

ok so bestie, this is a page from the Kernel API Manual — section 9 — and it's literally all about bch_next_delay, which is your little rate-limiting bestie in the kernel. it updates the ratelimiting stats and then tells you how long to chill before doing more work. slay. ✨

---

🌸 NAME 🌸

bch_next_delay — update ratelimiting statistics and calculate next delay 🎀

---

🦋 SYNOPSIS 🦋

uint64_t bch_next_delay (struct bch_ratelimit *d , uint64_t done );

like, yes, that's the whole signature. she's little but she's doing the most. 💖

---

⭐ ARGUMENTS ⭐

• d — the struct bch_ratelimit to update. this is the main character of the whole function ngl 👑
• done — the amount of work done, in arbitrary units. yes, arbitrary — the units are whatever you and your code decided they are, no cap 🙈

---

🔥 DESCRIPTION 🔥

Okay so here's the tea: bch_next_delay increments d by the amount of work done — that's your done value — and then returns how long to delay in jiffies until the next time to do some work. ⏳

That's it. That's the whole vibe. It's giving "accounting + scheduling bestie" energy. Lowkey iconic. 💅
