🌸 NAME 🌸

enum nvme_resv_cptpl — Reservation Register - Change Persist Through Power Loss State 🎀

like. that's the whole name. it's giving "my reservations survive a power cycle??" ✨

---

🦋 SYNOPSIS 🦋

enum nvme_resv_cptpl {
    NVME_RESERVATION_CPTPL_NO_CHANGE ,
    NVME_RESERVATION_CPTPL_CLEAR ,
    NVME_RESERVATION_CPTPL_PERSIST

};

ikr, three whole constants, we are FED 🍓

---

✨ Constants ✨

slay, here's the lineup. one bullet per constant, no skips, no cap 💅

• NVME_RESERVATION_CPTPL_NO_CHANGE — literally nothing happens. no change to PTPL state. it's the "leave me alone i'm fine" option 🙈
• NVME_RESERVATION_CPTPL_CLEAR — okay so on a power on: reservations are released and registrants are cleared. it's a full lil reset, everything goes bye-bye 💀
• NVME_RESERVATION_CPTPL_PERSIST — the main character option 👑 reservations and registrants persist across a power loss. they stay. they're iconic. they refuse to leave the group chat 🫶

ngl bestie, this enum is the one you set when you're registering a reservation and you need to tell the controller what should happen to your PTPL state. NO_CHANGE = chill, CLEAR = wipe it on power on, PERSIST = it survives, periodt. pick wisely, the vibes are load-bearing 🌈
