💖 is_power_of_2(9) 💖

okay so bestie, welcome to the kernel API manual — this one's is_power_of_2, and yes it does exactly what it says on the tin 🎀

---

✨ NAME ✨

is_power_of_2 — check if a value is a power of two

Like, literally just a vibe check for your integers 💅

---

🦋 SYNOPSIS 🦋

is_power_of_2 (n );

no cap, that's the whole shape of it — you hand it an n, it gives you an answer 🔥

---

🌸 ARGUMENTS 🌸

• n — the value to check 👀 (this is the one the function is judging, be nice to it)

---

🧚 DESCRIPTION 🧚

So what it does is determine whether some value is a power of two 🌈. And here's the part that matters, okay, listen: zero is *not* considered a power of two. Like, not even a little bit. Zero does not get to sit with the powers of two at lunch 💀.

Return: true if n is a power of 2, otherwise false. Simple as that, no cap, periodt ✨

bestie pls remember: 0 → false. That asterisk in the original is doing work, don't let anyone tell you otherwise 🫶
