ttm_tt_clear_backed_up(9)

💅 ttm_tt_clear_backed_up(9) — from the Kernel API Manual, bestie

Okay so real talk, we're in the ttm_tt_clear_backed_up(9) page today, and honestly? It's a little one. A tiny icon. But she matters, so let's give her the attention she deserves. ✨

🌸 NAME 🌸

ttm_tt_clear_backed_up — the function that clears the backed-up status on a ttm_tt. That's it, that's the whole vibe check. 🎀

---

🦋 SYNOPSIS 🦋

void ttm_tt_clear_backed_up (struct ttm_tt *tt );

Yes she returns void. No notes, no drama, she just does the thing and leaves. 👑

---

💖 ARGUMENTS 💖

• tt — the struct ttm_tt. That's your girl right there, the one whose backed-up status is getting cleared. 🫶

---

✨ DESCRIPTION ✨

So here's the tea: drivers can call this function to clear the backed-up status. That's the whole point of her existence, fr fr.

When would you even do that? Lowkey the classic case is before destroying or re-validating a purged tt — like, tidy up the status first, then go do the dramatic main-character thing. 💅
