💖 NAME 💖

struct nvme_lm_nvme_controller_state_data — bestie, this is the NVMe Controller State data structure ✨ and what it does is describe the state of a NVMe Controller's I/O Submission and I/O Completion queues. That's it, that's the vibe. No cap. 🦋

---

✨ SYNOPSIS ✨

struct nvme_lm_nvme_controller_state_data {
    struct nvme_lm_nvme_controller_state_data_header hdr;
    union {
      struct nvme_lm_io_submission_queue_data sqs[0];
      struct nvme_lm_io_completion_queue_data cqs[0];
    };
 };

🎀 Members 🎀

Lowkey the whole personality of this struct is right here, so let's go member by member, no skips, periodt 💅

• hdr — the Header. yes queen, every good struct starts with one 👑
• {unnamed_union} — anonymous. she has no name and she doesn't need one fr fr 🙈
• sqs — the I/O Submission Queue list 🍓
• cqs — the I/O Completion Queue list 🌸

---

not me being obsessed with a data structure that literally just holds a header and two queue lists... and yet?? iconic. the way that hdr sits at the top like the main character and the union does its little anonymous thing underneath 🫶
