mdiobus_alloc_size(9)

💖 NAME 💖

mdiobus_alloc_size — bestie, this is the one that allocates a mii_bus structure ✨

So like, the manual is the "Kernel API Manual" and the function is mdiobus_alloc_size, and it's the little allocator that could 🫶

---

✨ SYNOPSIS ✨

struct mii_bus * mdiobus_alloc_size (size_t size );

That's the whole vibe check right there 👑

---

🎀 ARGUMENTS 🎀

• size — the extra amount of memory you wanna allocate for private storage 🧺 Like, if it's non-zero, then bus->priv is points to that memory. (Yes, the original says "is points to" — I'm not gonna lie, that's giving typo core 💀 but I refuse to change a single character of the facts. It means bus->priv points at that memory, iykyk.)

---

🌸 DESCRIPTION 🌸

Okay so picture this: a bus driver is like "bestie I need a mii_bus structure to fill in" and this function is what gets called to allocate one 💅 That's it. That's the whole job. Iconic honestly.
