PROBE::IOSCHEDULER.ELV_NEXT_REQUEST(3stap)

💖 probe::ioscheduler.elv_next_request(3stap) 💖

okay bestie, so this is one of the IO Scheduler and block IO Taps pages — part of the SystemTap tapset reference, and it's genuinely so cute and small. no cap. 🎀

---

✨ NAME ✨

probe::ioscheduler.elv_next_request — fires when a request is retrieved from the request queue 🦋

like... the moment the scheduler reaches into the queue and pulls a request out? that's the moment. that's the moment. main character energy fr fr.

---

✨ SYNOPSIS ✨

probe ioscheduler.elv_next_request {}

yes it's literally just that. no args, no drama, just vibes. she takes no parameters and she doesn't need any 💅

---

✨ VALUES ✨

the numbers/strings you can read inside this probe, bestie:

• elevator_name — the type of I/O elevator that's currently enabled 👑 (iykyk, the elevator is the whole scheduling algorithm doing the ordering of requests)
• name — the name of the probe point 🌸

---

✨ SEE ALSO ✨

• tapset::ioscheduler(3stap) — go read the whole family, they're iconic 🫶

---

reminder bestie: this is the tapset reference, so everything here is exactly as written — don't go inventing extra values, the probe gives you elevator_name and name and that's the whole menu 😭💀

and that's the page!! 💜 this was SystemTap Tapset Reference, Version, September 2026 — mwah, slay, periodt. go probe some requests, you absolute legend ⭐🌈💖
