qla4xxx_con...a_addressing(9)

💅 qla4xxx_config_dma_addressing(9)

okay so this is a page straight outta the Kernel API Manual, and bestie, it is short but it's iconic. It's about one little function that sets up how the OS does DMA addressing. That's it. That's the whole vibe. 🎀

---

✨ NAME ✨

qla4xxx_config_dma_addressing — literally just configures the OS DMA addressing method. That's the entire job description, no cap. 🦋

---

🌸 SYNOPSIS 🌸

void qla4xxx_config_dma_addressing (struct scsi_qla_host *ha );

Notice the void bestie — this one doesn't hand you anything back. It just does the thing and dips. 💅

---

💖 ARGUMENTS 💖

• ha — the HA context. That's it, that's the whole parameter list. One (1) argument, main character energy. 👑

ngl there's no OPTIONS, no ENVIRONMENT, no EXIT STATUS, no BUGS section on this one — it's a minimalist queen. What you see is what you get. 🙈
