_scsih_raid_device_add(9)

💖 _scsih_raid_device_add(9) 💖

okay so welcome to the Kernel API Manual, bestie — manual section 9, kernel-space, no userland nonsense here 🫶. This little page is all about one function: _scsih_raid_device_add. It's short. It's sweet. It does exactly one thing and honestly? Iconic behavior.

---

✨ NAME ✨

_scsih_raid_device_add — add raid_device object 💅

---

🌸 SYNOPSIS 🌸

void _scsih_raid_device_add (struct MPT3SAS_ADAPTER *ioc , struct
_raid_device *raid_device );

like, that's it. returns void, so there's literally nothing to check. she just does it 🔥

---

🫶 ARGUMENTS 🫶

• ioc — the per adapter object, aka the whole vibe of the adapter she's working on
• raid_device — a raid_device object, the actual little guy getting added

---

🎀 DESCRIPTION 🎀

So what happens? This is added to the raid_device_list link list. That's the whole description. No cap, that's the entire character arc 😭 — she takes the raid_device and she links it into raid_device_list. Main character energy, zero plot twists.
