✨ ap_queue_usable(9) ✨

okay so this is the Kernel API Manual page for ap_queue_usable(9) — manual name folded in at the top, cute and accounted for 🫶 No cap, we're about to do a tiny vibe check on a queue.

🌸 NAME 🌸

• ap_queue_usable — check if the queue is usable just now. Like, right this second, bestie 💅

✨ SYNOPSIS ✨

bool ap_queue_usable (struct ap_queue *aq );

💖 ARGUMENTS 💖

• aq — the AP queue device to test for usability. This function is intended for the scheduler to query if it makes sense to enqueue a message into this AP queue device by calling ap_queue_message. The perspective is, like, very short-term — the state machine and the device state(s) may change at any time. So don't get attached to the answer, bestie 😭
