ibmvfc_adisc_timeout(9)

💅 ibmvfc_adisc_timeout(9) ✨

okay so we're in the Kernel API Manual bestie, and this page is all about ibmvfc_adisc_timeout — one little timer callback that handles an ADISC timeout. no cap, it's short but it does things. 🎀

---

🌸 NAME 🌸

ibmvfc_adisc_timeout — Handle an ADISC timeout. that's literally the whole job description and she owns it 💅

---

✨ SYNOPSIS ✨

void ibmvfc_adisc_timeout (struct timer_list *t );

---

🦋 ARGUMENTS 🦋

• t — the ibmvfc target struct 🎯 (yes, that's what the manpage says it is, and we're not arguing with the manpage)

---

🔥 DESCRIPTION 🔥

okay so picture this: an ADISC times out 😭. What do we do? We send a cancel. simple as that.

But then — and this is the part that gives main character energy — if the cancel also times out, we reset the CRQ. periodt. 💀

And when the ADISC finally comes back as cancelled, we log back into the target. that's it, that's the flow 🫶

no cap, that's the entire function. three little steps and she ate 👑
