vdo_waitq_de...hing_waiters(9)

💖 NAME 💖

okay so we're in the Kernel API Manual, page vdo_waitq_de...hing_waiters(9), and the whole vibe is this: vdo_waitq_dequeue_matching_waiters removes all waiters that match based on the specified matching method and appends them to a vdo_wait_queue. That's it. That's the mission. 💅

✨ SYNOPSIS ✨

no cap, here's the exact signature:

void vdo_waitq_dequeue_matching_waiters (struct vdo_wait_queue *waitq ,
       vdo_waiter_match_fn waiter_match , void *match_context , struct
       vdo_wait_queue *matched_waitq );

🎀 ARGUMENTS 🎀

okay bestie, here's the cast:

• waitq — the vdo_wait_queue to process. This is the queue getting the matching-waiter treatment.
• waiter_match — the method to determine matching. It's the little rule that decides who gets picked. 👑
• match_context — contextual info for the match method. Basically the extra tea that waiter_match needs.
• matched_waitq — a wait_waitq to store matches. Yes, that's the exact spelling on the page; the matches get parked there. 🫶
