libnvme(2)

💖 NAME 💖

ok so bestie, gather round — this one's the manual page for struct nvme_fdp_ruh_status_desc, aka the Reclaim Unit Handle Status Descriptor 🫶 it lives in the libnvme API manual (yep, libnvme(2), section 2, C library vibes) and it's literally just a lil struct that tells you how a reclaim unit handle is doing. no cap. ✨

---

✨ SYNOPSIS ✨

here's the shape of it, character for character, don't touch a thing:

struct nvme_fdp_ruh_status_desc {
    __le16 pid;
    __le16 ruhid;
    __le32 earutr;
    __le64 ruamw;
    __u8 rsvd16[16];
 };

ok lowkey look at those little endian types 👀 __le16, __le32, __le64 — the byte order is doing its own thing and it's iconic for it. 💅

🌸 Members 🌸

every field, bestie, in order, no skipping, i promised:

• pid — the Placement Identifier 🎀 that's its whole job, that's the vibe.
• ruhid — the Reclaim Unit Handle Identifier 🦋 yes it's the handle for the reclaim unit, and yes the naming is exactly what it says on the tin.
• earutr — the Estimated Active Reclaim Unit Time Remaining ⏳ it's giving "how much time left" energy, estimated, active, reclaim-unit flavored.
• ruamw — the Reclaim Unit Available Media Writes 📝 writes! media! available! the whole vibe check in one field.
• rsvd16 — Reserved 🙈 aka the [16] bytes of pure "not me, don't perceive me", do not touch, do not read, do not write, just let it exist peacefully please.

heads up bestie: rsvd16 is Reserved — reserved means hands off, fr fr. don't go writing your own lore into those bytes. 😭
