💖 libnvme(9) — API Manual 💖

okay bestie, buckle UP, we're diving into libnvme's manual pages and honestly? it's giving documentation but make it serve. this one's all about one lil struct, and she's lowkey important. 🫶

---

✨ NAME ✨

struct nvme_resv_release_args — Arguments for the NVMe Reservation Release Command

like, literally just the lil bundle of args you hand over when you wanna release a reservation. that's her. that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

struct nvme_resv_release_args {
    __u64 crkey;
    __u32 *result;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_resv_rtype rtype;
    enum nvme_resv_rrela rrela;
    bool iekey;
 };

look at her. nine members. no notes. ✨

🦋 Members 🦋

okay so each field has a job and we're gonna give them all their moment, no skips, no shortcuts:

• crkey — the current reservation key you wanna release. like, the key you're currently holding. you gotta hand it back, bestie 🔑
• result — this is where the command completion result lands, straight from CQE dword0. the receipt of the operation, basically 🧾
• args_size — the size of struct nvme_resv_release_args itself. she knows her own measurements, iconic 💅
• fd — the file descriptor of the nvme device. your lil handle to the thing you're talking to 🔌
• timeout — timeout in ms. how long we're willing to wait before we're like... ok bye ⏳
• nsid — namespace identifier. which namespace we're on, no ambiguity 🎯
• rtype — the type of reservation to be create, see enum nvme_resv_rtype. (yes, the original says "to be create", and honestly? we're leaving it exactly as it is, fr fr 🫶)
• rrela — reservation release action, see enum nvme_resv_rrela. this is the how of the release 🎀
• iekey — set this to ignore the existing key. set it and she simply does not care about the key that's already there 🙈

ngl, if you're staring at enum nvme_resv_rtype and enum nvme_resv_rrela wondering what the actual options are, that's a whole other page. this one's just the args struct. iykyk 💀

(no SEE ALSO section in this page, bestie — just the struct, its members, and the vibes ✨)

and that's the whole page!! every single field accounted for, nothing skipped, nothing invented. main character struct energy only. 🌈💜
