ok so like — welcome to the Kernel API Manual, bestie 🎀 this one's a lil function page and honestly it's giving "small but mighty" energy. buckle up, it's gonna be quick but iconic ✨

🌸 NAME 🌸

round_jiffies_up_relative — a function that rounds jiffies up to a full second, no cap 🕐⬆️

---

✨ SYNOPSIS ✨

unsigned long round_jiffies_up_relative (unsigned long j );

---

🧚 ARGUMENTS 🧚

• j — the time, in (relative) jiffies, that's gonna get rounded 💫 this is the main character of the function fr

---

💖 DESCRIPTION 💖

okay so, real talk: this is the same as round_jiffies_relative — literally the same vibes — except it will never round down. never. not once. periodt 💅

which is lowkey so useful for timeouts where the exact time of firing does not matter too much, as long as they don't fire too early 😤 like, precision? not the vibe. but earliness? absolutely not, we don't do that here 🚫

think of it as the friend who's always a lil late but never early — and in this case that's exactly the point 🫶
