lpfc_sli_issue_abort_iotag(9)

🦋 lpfc_sli_issue_abort_iotag(9) 🦋

okay so bestie, welcome to the Kernel API Manual entry for lpfc_sli_issue_abort_iotag — yes the whole name, we're not abbreviating, she's iconic and she knows it 💅

---

✨ NAME ✨

lpfc_sli_issue_abort_iotag — Abort function for a command iocb 🛑

That's it, that's the whole vibe. She aborts. She's the abort function. For a command iocb. Periodt.

---

💫 SYNOPSIS 💫

int lpfc_sli_issue_abort_iotag (struct lpfc_hba *phba , struct
lpfc_sli_ring *pring , struct lpfc_iocbq *cmdiocb , void *cmpl );

Like, four arguments, one int coming back, no cap. Copy-paste safe, we do not "fix" the spacing here, that's literally how she's written 🙈

---

🎀 ARGUMENTS 🎀

• phba — Pointer to HBA context object. your main character struct fr 🫶
• pring — Pointer to driver SLI ring object. the ring she's living in 💫
• cmdiocb — Pointer to driver command iocb object. the command iocb in question, the one getting aborted 👑
• cmpl — completion function. the callback, the "what happens next" girlie 🌸

---

🔥 DESCRIPTION 🔥

So here's the tea ☕ — this function issues an abort iocb for the command iocb you hand it. That's the whole job. Abort iocb out the door for the provided command iocb, no extra drama 💅

But — and this is the part where you gotta pay attention, bestie — in case of unloading, the abort iocb will not be issued to commands on the ELS ring. Nope. Instead, the callback function shall be changed to those commands so that nothing happens when them finishes. Like the callback just gets swapped so it's a whole "nothing to see here" situation when they finish 😭 It's giving quietly ghosting your own commands, and honestly? That's on purpose. Don't fight it.

⚠️ Locking tea: this function is called with hbalock held and no ring_lock held (SLI4). Read that twice. hbalock yes, ring_lock no. Do not come for me if you mix that up 💀

And the return value? The function returns IOCB_SUCCESS when the command iocb is an abort request 👑 That's the check, iykyk.
