ibmvfc_tgt_adisc(9)

💅 ibmvfc_tgt_adisc — the ibmvfc_tgt_adisc(9) page, bestie edition 🎀

okay so this one's a kernel API manual page from the ibmvfc_tgt_adisc(9) club, and honestly? it's short, it's spicy, and the timer lore goes HARD. let's get into it 🦋

---

✨ NAME ✨

ibmvfc_tgt_adisc — the function that kicks off an ADISC for a specific target 💫

---

🌸 SYNOPSIS 🌸

void ibmvfc_tgt_adisc (struct ibmvfc_target *tgt );

like, that's it. that's the whole signature. she's void, she takes one thing, she does not return your texts 💜

---

🧚 ARGUMENTS 🧚

• tgt — the ibmvfc target struct. that's the vibe. that's the whole argument list. one (1) struct, no notes 🫶

---

🔥 DESCRIPTION 🔥

okay so here's the tea, and it's highkey important: when you send an ADISC you end up with two timers running. not one. two. main character energy times two, periodt 💅

timer number one is the timer living in the ibmvfc target struct. if this one fires, we send a cancel to the target. that's her whole job 🎀

timer number two is the timer on the ibmvfc event for the ADISC — and she's the longer one. so if that one fires? it means the ADISC timed out and our attempt to cancel it also failed. like, double flop. and because of that, we need to reset the CRQ 😭

so yeah: two timers, escalating consequences. don't @ me, just read the code iykyk 🔥
