megasas_flush_cache(9)

💅 megasas_flush_cache — from the Kernel API Manual, bestie ✨

Okay so picture this: it's a kernel API manual page, the star is megasas_flush_cache(9), and she's here to make your firmware actually tidy up after itself. Obsessed already? Same.

---

✨ NAME ✨

megasas_flush_cache — literally just asks the FW (that's firmware, iykyk) to flush all of its caches. That's it. That's the whole job. 🎀

---

🦋 SYNOPSIS 🦋

void megasas_flush_cache (struct megasas_instance *instance );

No cap, that's the whole signature. Returns void, so she doesn't even come back with receipts. 🙈

---

🌸 ARGUMENTS 🌸

• instance — the adapter soft state 💖 like, the whole vibe of your adapter, bundled up in one struct. Hand her over and she knows what to do.

💀 Also, the actual kernel file lives at ./drivers/scsi/megaraid/megaraid_sas_base.c — go say hi, she's the source of truth, no cap.

And that's the whole page, bestie — short, sweet, and she ate. 🌈 This little masterpiece ships from ./drivers/scsi/megaraid, version stamped October 2026, and yes she's still signing off as megasas_flush_cache(9) because main character energy never dies 👑💅
