💅 trace_block_plug(9) — a Kernel API Manual moment ✨

okay so bestie, we're in the Kernel API Manual today, and this page is short but it eats. no cap. let's get into it 🫶

✨ NAME ✨

trace_block_plug — literally just keeping operation requests chillin' in the request queue 🎀

🌸 SYNOPSIS 🌸

void trace_block_plug (struct request_queue *q );

yeah that's the whole thing. one function, one arg, void return. minimalist icon behavior 💅

🦋 ARGUMENTS 🦋

  • q — the request queue you're plugging. that's it, that's the argument, she's the request queue to plug 🎀

🔥 DESCRIPTION 🔥

so what does it do? it plugs the request queue q. periodt.

and by "plug" we mean: do not allow block operation requests to be sent to the device driver. nope. not today. instead, requests get accumulated in the queue so the throughput performance of the block device goes up 📈✨ it's giving "let it marinate" and honestly? iconic.

ngl this one is a one-trick pony but the trick is genuinely good — hold the requests, let them pile up, then let the throughput glow-up happen 💖

👑 SEE ALSO 👑
