_ctl_getiocinfo(9)

💖 NAME 💖

okay so bestie, welcome to _ctl_getiocinfo(9) from the Kernel API Manual — this function is literally the main handler for the MPT3IOCINFO opcode, no cap. It's giving "adapter info desk" energy and I'm obsessed. ✨

🛠️ SYNOPSIS 🛠️

Here's the exact signature, bestie — copy it character for character, do not improvise:

long _ctl_getiocinfo (struct MPT3SAS_ADAPTER *ioc , void __user *arg );

🌸 ARGUMENTS 🌸

• ioc — the per adapter object, aka the adapter's own little main-character universe. 🪐
• arg — the user space buffer containing the ioctl content, aka the payload bestie. 🫶

the lore is deep, and every single link is here — no skipping, iykyk:
