💅 libnvme(9) — enum nvme_id_ctrl_ctratt 💅
okay bestie so this is one of those pages from the libnvme API manual (yeah, the one that shows up as libnvme(9) in your man viewer) and listen, it's literally just a big glowing list of controller attributes — like, the personality quiz the NVMe controller fills out about itself. 🦋 No functions to call, no drama, just the enum that names every bit and field of the CTRATT thing. Let's go. ✨
🌸 NAME 🌸
enum nvme_id_ctrl_ctratt — Controller attributes 👑

};like, yes, there's a stray blank line before the closing brace. iconic. we don't fix it, we respect it. 🫶

ngl there are no functions, no return values, no errno, no exit statuses on this page — it's purely a constant party. That's the whole vibe check. 💅
and that's the page bestie, no cap 🧚💜 — brought to you by the October 2026 edition of the libnvme(9) API manual, enum nvme_id_ctrl_ctratt and all its little bit-shifty children. go forth and mask responsibly. 🎀🌷
