__mpi3mr_ge..._by_perst_id(9)

💅 NAME 💅

okay so bestie, welcome to __mpi3mr_get_tgtdev_by_perst_id(9) — that's the page name — and it lives in the Kernel API Manual, section 9 (kernel girlies only 💜). What does it do? It gets you the tgtdev from the persist ID. Yes, that's the whole vibe. ✨

🌸 SYNOPSIS 🌸

struct mpi3mr_tgt_dev  * __mpi3mr_get_tgtdev_by_perst_id (struct
mpi3mr_ioc *mrioc , u16 persist_id );

like, that's literally it. no cap. 🎀

🦋 ARGUMENTS 🦋

• mrioc — the Adapter instance reference, i.e. your main character adapter 😌
• persist_id — the Persistent ID. the ID that persists. it's giving consistent 🫶

⭐ DESCRIPTION ⭐

so this is an accessor — it reaches in and retrieves a target device using its Persistent ID. one job, does it well, ate and left no crumbs 💅

and the important part: this is the Non Lock version 🔓 — no lock, just vibes. that's literally in the description so don't come for me.

👑 RETURN 👑

a target device reference. that's your answer. that's the whole gift 🎁
