mpi3mr_expander_node_add(9)

okay bestie, welcome to the mpi3mr_expander_node_add(9) page from the Kernel API Manual 💅 this one is about inserting an expander to the list, and we are keeping every single detail. no cap.

💖 NAME 💖

insert an expander to the list. that's the name, that's the vibe, periodt.

✨ SYNOPSIS ✨

void mpi3mr_expander_node_add (struct mpi3mr_ioc *mrioc , struct
       mpi3mr_sas_node *sas_expander );

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. your adapter's whole reference situation, bestie.
• sas_expander — Expander sas node. the expander's sas node, exactly like it says.

🔒 CONTEXT 🔒

heads up: this function will acquire sas_node_lock. so yes, it is grabbing that lock, no cap.

🦋 DESCRIPTION 🦋

it is adding a new object to the ioc->sas_expander_list. the new object goes into that list, and that is the move 🌸

🌈 RETURN 🌈

None. literally none — no return value, bestie.
