✨ SYNOPSIS ✨

void ttm_tt_mark_for_clear (struct ttm_tt *ttm);

that's it. that's the function. a whole little void icon returning nothing because it's too busy being helpful 💅

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function marks pages for clearing, which means that the next time the page vector gets populated, those pages are gonna be cleared. that's it, that's the whole personality. no returning values, no drama, just flagging pages so future-you (or future-populate) knows what's up 🔥

it's lowkey the "remind me later" of kernel memory management and i'm obsessed 💖
