STRUCT DEV_DAX_RANGE(9)

✨ struct dev_dax_range(9) ✨

okay so bestie, welcome to struct dev_dax_range(9) — this is the Kernel API Manual entry for a lil struct whose whole personality is being a tuple representing a range of memory used by dev_dax. that's it, that's the vibe 🎀

---

🌸 NAME 🌸

struct dev_dax_range — a tuple representing a range of memory used by dev_dax. literally just a cute little trio of fields holding down one memory range, no cap 💅

---

🦋 SYNOPSIS 🦋

struct dev_dax_range {
    unsigned long pgoff;
    struct range range;
    struct dax_mapping *mapping;
 };

look at her. three members, immaculate energy, not a single wasted line ✨

---

👑 Members 👑

• pgoff — the page offset. yes bestie, the page offset, not the byte offset — she's counting in pages 🍓
• range — the resource-span. this is the actual stretch of memory we're talking about 🌈
• mapping — a reference to the dax_mapping for this range. she knows a guy, and the guy is a dax_mapping 💜

ngl this struct is short and sweet — the way she holds pgoff, range and mapping together? main character energy. periodt 💀

and that's the whole page, bestie — brought to you from ./drivers/dax on the October 2026 drop. mwah, go forth and range responsibly 🌸💖⭐
