✨ qla2x00_erase_flash(9) ✨

okay so this is a page from the Kernel API Manual bestie, and we're talking about qla2x00_erase_flash — the little function that literally just yeets the flash 🫶 buckle up, it's short but it's iconic.

💖 NAME 💖

qla2x00_erase_flash — Erase the flash. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int qla2x00_erase_flash (struct qla_hw_data *ha , uint8_t man_id ,
       uint8_t flash_id );

three args, one int coming back at you, no cap ✨

---

🦋 ARGUMENTS 🦋

• ha — the HA context 💅 like, the whole hardware situation gets passed in here, she's the main character of this call.
• man_id — Flash manufacturer ID 🏭 literally just tells you who made the flash chip, iykyk.
• flash_id — Flash ID 🌈 the actual ID of the flash itself, not to be confused with the manufacturer one (we love a distinction).

---

🔥 DESCRIPTION 🔥

Returns 0 on success, else non-zero. periodt. 💀

ngl that's the entire description — no lore, no backstory, just a return value doing its little thing. zero means we ate, anything else means something went sideways and you should probably look at it 🙈

💡 friendly reminder: erasing flash is not a reversible situation — she's doing exactly what the name says, so know what you're calling before you call it 🫶
