💖 pt_table_oa_lg2sz(9) 💖

okay bestie, so this one is from the Kernel API Manual (section 9, kernel-land, very demure) and it's genuinely such a neat little helper: pt_table_oa_lg2sz — "Return the VA/OA size of the entire table". iconic name, iykyk 🎀

---

✨ SYNOPSIS ✨

unsigned int pt_table_oa_lg2sz (const struct pt_state *pts );

that's it. one argument. lowkey elegant, ngl 💅

---

🌸 ARGUMENTS 🌸

• pts — the current level. that's literally it, that's the whole parameter, she's a const struct pt_state * and she's just here to tell us where we are 🦋

---

💫 DESCRIPTION 💫

so basically: this function returns the size of the VA decoded by the entire table level. that's the vibe. that's the whole function. no extra lore, no hidden side quests, just a straight-up size report for the whole table level 💖

fr fr that's the entire description — it's a short king, we respect it 👑
