__mpi3mr_exp...nd_by_handle(9)

💖 NAME 💖

okay bestie, this page is __mpi3mr_exp...nd_by_handle(9) from the Kernel API Manual, and the function is __mpi3mr_expander_find_by_handle — literally “expander search by handle.” Periodt. ✨

🌸 SYNOPSIS 🌸

struct mpi3mr_sas_node * __mpi3mr_expander_find_by_handle (struct
mpi3mr_ioc *mrioc , u16 handle );

🎀 ARGUMENTS 🎀

• mrioc — the adapter instance reference, aka the main character adapter pointer 💅
• handle — the firmware device handle of the expander; this is the handle we’re searching with, no cap.

🦋 CONTEXT 🦋

Context check, bestie: the caller should acquire sas_node_lock 🫶

✨ DESCRIPTION ✨

So here’s the serve: this searches for the expander device based on handle, then returns the sas_node object. That’s the move. 💖

🔥 RETURN 🔥

Return vibe check: an expander sas_node object reference, or NULL. That’s it, that’s the whole answer. 🌈
