rvt_div_round_up_mtu(9)

💅 rvt_div_round_up_mtu(9) — Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual, and honestly? it's a tiny lil icon. one function, two arguments, one job. she's giving "does exactly what it says on the tin" and we respect that fr fr.

✨ NAME ✨

rvt_div_round_up_mtu — round up divide 🦋

no like literally that's it, that's the whole vibe. it rounds up. it divides. it's a round-up divide. slay.

---

🌸 SYNOPSIS 🌸

u32 rvt_div_round_up_mtu (struct rvt_qp *qp , u32 len );

so she takes a struct rvt_qp *qp and a u32 len, and she hands you back a u32. clean. simple. iconic. 💖

---

🫶 ARGUMENTS 🫶

• qp — the qp pair 👑
• len — the length 🍓

that's the whole guest list, bestie. two parameters and they're both doing their part.

---

🔥 DESCRIPTION 🔥

Perform a shift based mtu round up divide ✨

ngl that's the full description and she ate. it's a shift based round up divide for the mtu — so she's doing that lil bit-shifty math move to round your value up instead of down. no cap, that's the entire plot. 🧚
