STRUCT ND_NAMESPACE_COMMON(9)

💅 struct nd_namespace_common(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct nd_namespace_common, and ngl it's kind of the main character of namespace core infrastructure. Let's get into it 🫶

---

🌸 NAME

struct nd_namespace_common — core infrastructure of a namespace 💖

---

✨ SYNOPSIS

struct nd_namespace_common {
    int force_raw;
    struct device dev;
    struct device *claim;
    enum nvdimm_claim_class claim_class;
    int (*rw_bytes)(struct nd_namespace_common *, resource_size_t
offset, void *buf, size_t size, int rw, unsigned long flags);
 };

like, that's the whole vibe right there 👑

🎀 Members

okay so here's who's who in this struct, no cap 🔥

• force_raw — when this is set, it tells the namespace to ignore every other personality (think btt, bestie) 🫣 like sorry not sorry, we're going raw.
• dev — the device model node 💻 literally the device-model representation of this thing.
• claim — when set, it means another personality has already taken ownership of the namespace 💀 so like… it's taken, okay?
• claim_class — restricts the claim type to a given class 🔒 keeps things from getting messy.
• rw_bytes — a function pointer that gives you access to the raw namespace capacity with byte-aligned transfers ✨ so if you need it byte by byte, this is the icon.
