STRUCT FOLIO_ITER(9)

🌸 NAME 🌸

okay bestie, welcome to the struct folio_iter(9) page from the Kernel API Manual 💅 this one is literally about State for iterating all folios in a bio. no cap.

✨ SYNOPSIS ✨

       struct folio_iter {
           struct folio *folio;
           size_t offset;
           size_t length;
        };

👯 MEMBERS 👯

• folio — the current folio we're iterating, bestie. it's NULL after the last folio. 💀
• offset — the byte offset within the current folio. 📏
• length — the number of bytes in this iteration (will not cross folio boundary). no boundary-crossing drama here, periodt. ✨
