folioq_full(9)

✨ NAME ✨

okay so bestie, this is folioq_full(9) from the Kernel API Manual — it’s the little function that queries if a folio queue segment is full. 💅

✨ SYNOPSIS ✨

bool folioq_full (struct folio_queue *folioq );

✨ ARGUMENTS ✨

• folioq — the segment you’re querying 👀

✨ DESCRIPTION ✨

So folioq_full queries if a folio queue segment is fully occupied. That’s the whole assignment, and it ate. 💖

Important vibe check, no cap: this does not change if folios are removed from a segment. Like, it is not out here recalculating when things get taken out — periodt. 🎀
