sq_to_tg(9)

okay so bestie, welcome to sq_to_tg(9) from the Kernel API Manual 💖 this one is short, sweet, and lowkey iconic — we're checking which throttle group a service queue belongs to. periodt ✨

💖 NAME 💖

sq_to_tg — return the throl_grp the specified service queue belongs to. no cap, that's the exact spelling from the page, and we're keeping it 🫶

✨ SYNOPSIS ✨

struct throtl_grp * sq_to_tg (struct throtl_service_queue *sq );

🎀 ARGUMENTS 🎀

• sq — the throtl_service_queue of interest 👀 aka the queue we're asking about.

🦋 DESCRIPTION 🦋

Return the throtl_grp that sq belongs to. that's the whole vibe ✨

But bestie, plot twist: if sq is the top-level one embedded in throtl_data, then NULL is returned 💀 so NULL is literally the whole answer in that case.
