💅✨ pvr_page_tab...try_is_valid(9) ✨💅

okay bestie, welcome to the Kernel API Manual — this is the glow-up page for pvr_page_table_l2_entry_is_valid, and yes the truncated title is the whole vibe, she's mysterious like that 🎀

🌸 NAME 🌸

pvr_page_table_l2_entry_is_valid — the little vibe check that tells you whether a level 2 page table entry is marked as valid 💖

🦋 SYNOPSIS 🦋

bool pvr_page_table_l2_entry_is_valid (struct pvr_page_table_l2 *table ,
u16 idx );

🎀 ARGUMENTS 🎀

• table — your target level 2 page table. the main character, the one we're inspecting 👑
• idx — index of the entry to check. which one we're looking at, bestie 🔍

💜 DESCRIPTION 💜

so here's the tea: idx is not checked in here. like, at all. ngl it's fully the caller's responsibility to make sure idx actually points to a valid index inside table before calling this function. no cap — if you don't do your homework, that's on you, not her 😭

fr fr: this function trusts you. don't make it regret that. 🙈
