onenand_inva...te_bufferram(9)

💅 onenand_invalidate_bufferram(9) 💅

okay bestie, so this little cutie comes to you straight from the Kernel API Manual, and honestly? she's a tiny one. like, blink and you'll miss her. but we're gonna give her the full main-character treatment anyway because every function deserves love 💖

---

🎀 NAME 🎀

onenand_invalidate_bufferram — like, literally [GENERIC] Invalidate BufferRAM information ✨ (yes, the [GENERIC] is part of the name, keep it, she earned it)

---

🦋 SYNOPSIS 🦋

here's the whole signature, no cap:

void onenand_invalidate_bufferram (struct mtd_info *mtd , loff_t addr ,
       unsigned int len );

void return, three args, that's the vibe 🌸

---

🍓 ARGUMENTS 🍓

• mtd — the MTD data structure, i.e. your whole device's little info packet 👑
• addr — the start address you're invalidating, like where the drama begins 📍
• len — how long the invalidated stretch is, the length, the span, the amount 🫶

---

🔥 DESCRIPTION 🔥

okay so the entire job description here is: Invalidate BufferRAM information 💀

that's it. that's the whole plot. no extra lore, no secret side quests, no hidden options — I'm not gonna sit here and invent behaviour that isn't in the source, because that would be lying to you and we don't do that in this group chat 🙈

just know that when BufferRAM info needs to be marked as no-longer-trustworthy, this is the girl who does it. iconic, lowkey. ✨

🌈 SEE ALSO 🌈

she lives in the kernel file ./drivers/mtd/nand/onenand/onenand_base.c — go say hi 🫶

and because she's part of a huge family, here's the entire extended friend group, bestie, everybody gets named, no one gets left out 💜

ok that's the whole page, bestie — she's short, she's sweet, she invalidates BufferRAM info and she goes home. periodt. 💅

and before I go: this lil masterpiece comes from ./drivers/mtd/nand/onenand, dated October 2026, and the page name is onenand_invalidate_bufferram(9) in case you forgot already 😭 mwah, bye 🎀✨🦋
