💖 libnvme — struct nvme_dsm_range 💖

okay bestie, welcome to the libnvme API manual, chapter: one (1) extremely specific little struct. it's called nvme_dsm_range and no, it's not about your situationship, it's about Dataset Management - Range Definition. yep. range definition. we're defining a range. iconic behaviour tbh 🎀

✨ NAME ✨

struct nvme_dsm_range — Dataset Management - Range Definition 🦋

that's it. that's the whole name. short, sweet, slays.

 };

three fields. one struct. main character energy ✨
