expr_invalidate_all(9)

💅 expr_invalidate_all(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the Big Kernel Pages now, put your hair up, we're learning something iconic today. This one is called expr_invalidate_all, and honestly? The name is giving exactly what it is. No plot twists. ✨

---

🎀 NAME 🎀

expr_invalidate_all — invalidate all cached expression values 🫶

Like, every single one of them. Not a vibe check on a few of them. All of them. periodt.

---

✨ SYNOPSIS ✨

void expr_invalidate_all (void );

That's it. That's the whole thing. A void function that takes void. She does not want your arguments, she does not want your parameters, she wants nothing from you and returns nothing to you. Queen behavior honestly. 👑

---

🌸 ARGUMENTS 🌸

• void — no arguments 🎀

Zero. Zilch. Nada. Empty list energy. You literally cannot pass anything here, so don't even try, bestie — there's nothing to fill in, no little placeholders to swap out, no arg1, no arg2. Just call it and go. 💀

---

🦋 SEE ALSO 🦋

• The kernel file ./scripts/kconfig/expr.c — that's where the whole situation lives, iykyk
• expr_lookup(9)
• expr_calc_value(9)

Go read those two if you want the full lore — expr_lookup(9) and expr_calc_value(9) are literally right there in the same file, holding hands with this one. 🌈

---

ngl there is no deeper meaning hiding in here — description says what it does, arguments say there are none, and the SEE ALSO is a two-item friend group. You ate this page up in like ten seconds. 💅

---

and that's a wrap, bestie!! 🌸 This page comes to you from the source ./scripts/kconfig, dated October 2026 — the expr_invalidate_all(9) era, a truly iconic time to be alive. Go forth and invalidate those cached expression values, you absolute main character. 💜🎀✨
