STRUCT ND_NAMESPACE_PMEM(9)

✨ NAME ✨

struct nd_namespace_pmem — the namespace device for dimm-backed interleaved memory 💖

okay bestie, this is a page from the Kernel API Manual, and it's literally all about that struct nd_namespace_pmem life. no cap, it's giving namespace device for dimm-backed interleaved memory, and we're gonna go through every member together 🫶

🌸 SYNOPSIS 🌸

struct nd_namespace_pmem {
    struct nd_namespace_io nsio;
    unsigned long lbasize;
    char *alt_name;
    uuid_t *uuid;
    int id;
};

💅 MEMBERS 💅

• nsio — the device and system physical address range to drive. that's the whole vibe of this member, bestie ✨
• lbasize — logical sector size for the namespace in block-device-mode. it's an unsigned long, and it's literally holding the logical sector size info 💫
• alt_name — namespace name supplied in the dimm label. yep, a char *, and it's the name from the dimm label 🎀
• uuid — namespace name supplied in the dimm label. it's a uuid_t *, and yes, the description matches alt_name exactly — i don't make the rules, i just report them 💀
• id — ida allocated id. an int, allocated by ida, iconic behaviour 👑
