qla4_8xxx_watchdog(9)

💅 NAME 💅

qla4_8xxx_watchdog(9) — straight out of the Kernel API Manual, bestie. What does it do? It polls dev state. That's it, that's the whole gig. ✨

---

🎀 SYNOPSIS 🎀

void qla4_8xxx_watchdog (struct scsi_qla_host *ha );

Notice the void — she gives nothing back, she's just here to do the thing and dip. 💁‍♀️

---

🦋 ARGUMENTS 🦋

• ha — a pointer to the host adapter structure. That's your whole world right there, babes. 🫶

---

🔥 CONTEXT 🔥

Interrupt.

Yep. This is interrupt-context code, so clock in, do your little poll, and clock out — that's the energy the kernel is expecting from you. ⚡
