sas_ex_discover_devices(9)

✨ NAME ✨

Welcome to the sas_ex_discover_devices(9) page from the Kernel API Manual, bestie — this is the one that’s literally about discovering devices attached to this expander. The official NAME vibe is: sas_ex_discover_devices — discover devices attached to this expander. No cap. 🎀

🌸 SYNOPSIS 🌸

int sas_ex_discover_devices (struct domain_device *dev , int single );

🦋 ARGUMENTS 🦋

• dev — pointer to the expander domain device. That’s the expander bestie in question. 💖
• single — if you want to do a single phy, else set to -1; that’s the whole assignment. ✨

💅 DESCRIPTION 💅

Okay so what this does: it configures this expander for use with its devices, and it registers the devices of this expander. That’s the entire glow-up — configure this expander for its devices, then register this expander’s devices. Iconic, focused, and lowkey doing exactly what it says on the tin. 🫶
