💖 qla2300_intr_handler(9) 💖

okay so this is a page from the Kernel API Manual, and honestly? it's a whole little legend. it's qla2300_intr_handler(9) — say that three times fast, i dare you 🫶

---

✨ NAME ✨

qla2300_intr_handler — the girlie who processes interrupts for the ISP23xx and ISP63xx. no cap, that's the whole job description 💅

---

🎀 SYNOPSIS 🎀

irqreturn_t qla2300_intr_handler (int irq , void *dev_id );

the way this signature just sits there being iconic. irqreturn_t in, irqreturn_t out. periodt.

---

🌸 ARGUMENTS 🌸

• irq — the interrupt number, bestie. that's the whole vibe of this one.
• dev_id — the SCSI driver HA context 🦋 (yes it's a void *, no we do not ask questions, it's fine, it's giving "trust me")

---

💜 DESCRIPTION 💜

so basically, the system calls this whenever the host adapter generates an interrupt. that's it. that's the tea ☕ the hardware pings, and this function is the main character who answers.

and when it's done doing its thing, it returns the handled flag. lowkey the most well-adjusted function on this whole list tbh 🧚
