ibmvfc_timeout(9)

💅 ibmvfc_timeout(9) — bestie's guide to the kernel API manual ✨

okay so hi, we're reading ibmvfc_timeout, section 9 of the kernel API manual, and honestly? it's a short one. a little snack. a single bite of a function. but we're gonna do it right, so grab your iced coffee 🍓 and let's go.

---

✨ NAME ✨

ibmvfc_timeout — the internal command timeout handler 🔥 (yes that's literally the whole name description, she's concise, she's iconic, periodt)

---

🎀 SYNOPSIS 🎀

void ibmvfc_timeout (struct timer_list *t );

that's it. that's the whole signature. void return, one arg, done. slay 💅

---

🦋 ARGUMENTS 🦋

• t — described on the page as a struct ibmvfc_event that timed out 👀

okay so real talk bestie — the SYNOPSIS up there says the param is a struct timer_list *t, and the ARGUMENTS line says it's a struct ibmvfc_event. both of those are literally what the page says. I'm not picking a favorite, I'm not fixing it, I'm just reporting. iykyk 🙈

---

🌸 DESCRIPTION 🌸

so when an internally generated command times out, this is the thing that gets called. that's the whole vibe check. internally generated command → times out → ibmvfc_timeout gets called. she's the one on timeout duty 👑

lowkey the most straightforward description on the whole page and I respect that energy fr fr.

also remember the file that started it all: ./drivers/scsi/ibmvscsi/ibmvfc-core.c — that's where this lives, go say hi 🧚

okay that's the page!! short and sweet, just like she deserves 💜 huge thank you to ./drivers/scsi/ibmvscsi for shipping this, dated very cutely as October 2026 — see you in the next manpage, bestie, mwah 🎀✨💖
