🎀 NAME 🎀

okay so bestie, welcome to the libnvme(9) API Manual ✨ — this page is all about struct nvme_exported_subsys_mgmt_data, aka the Subsystem Management Data Structure, used by the Manage Exported NVM Subsystem Send Grant Host Access and Revoke Host Access operations. iconic struct behavior, no cap 💅.

✨ SYNOPSIS ✨

struct nvme_exported_subsys_mgmt_data {
    __u8 rsvd0[64];
    __le16 numhent;
    __le16 numense;
    __u8 rsvd68[188];
    __u8 entries[];
 };

🌸 Members 🌸

• rsvd0 — Reserved 🫶 like, literally reserved, bestie, don’t touch.
• numhent — Number of Host Entries (NUMHENT), and it shall be greater than 0h 👑.
• numense — Number of Exported NVM Subsystem Entries (NUMENSE), and it shall be greater than 0h 🌟.
• rsvd68 — Reserved 💅 again: reserved, reserved, reserved.
• entries — numhent entries of struct nvme_exported_subsys_mgmt_host_entry followed by numense entries of struct nvme_exported_subsys_mgmt_subsys_entry. Left as a raw byte buffer since the two variable-length lists have different element sizes and cannot both be expressed as fixed struct members - the caller walks entries using the sizes of those two struct types 🧚✨.

okay that’s the whole vibe, bestie 🫶 — this page came from libnvme(9) and the footer date is October 2026, so take that energy with you 💖💅
