translate_sense_reason(9)

💅 translate_sense_reason(9)

okay so bestie, welcome to the kernel API manual for translate_sense_reason — a little function living its best life in the <pink>Kernel API Manual</pink> section 9 of the man pages. Sit down, hydrate, and let's get into it 🫶

---

✨ NAME ✨

translate_sense_reason — translate a sense reason into T10 key, asc and ascq 🌸

Like, it takes your vibe-y internal reason code and turns it into the actual SCSI sense trio the world can read. It's giving translator bestie. 🎀

---

✨ SYNOPSIS ✨

void translate_sense_reason (struct se_cmd *cmd , sense_reason_t reason );

No cap, that's the whole signature. Copy it exactly, don't get creative with it 💅

---

✨ ARGUMENTS ✨

• cmd — the SCSI command in which the resulting sense buffer or SCSI status will be stored. Basically it's the lucky little command struct that gets to hold the receipts 📥✨
• reason — the LIO sense reason code. And okay, real talk, there's a spicy special case here: if this argument has the value TCM_CHECK_CONDITION_UNIT_ATTENTION, the function tries to dequeue a unit attention. But — and hear me — if dequeuing a unit attention fails because multiple commands are being processed concurrently, it sets the command status to BUSY. Concurrency said "not today" 💀

---

✨ RETURN ✨

0 upon success, or -EINVAL if the sense buffer is too small 😭

So if the sense buffer is too small, that's a -EINVAL, not a crash, not a shrug. Respect the buffer size, bestie. 🙈
