nvme_init_g...resv_persist(9)

💅 nvme_init_get_features_resv_persist — bestie, let's build that passthru command

okay so this is a page from the libnvme API manual, and the header up top is literally just the function name squished down to nvme_init_g...resv_persist(9) because apparently even manpage headers get tired and need a trim ✨ (the real, full name is the one right up there in the heading, no cap). Let's get into it 🫶

✨ NAME ✨

nvme_init_get_features_resv_persist — initialize the passthru command for Get Features - Reservation Persistence 💫

---

🎀 SYNOPSIS 🎀

void nvme_init_get_features_resv_persist (struct libnvme_passthru_cmd
*cmd , __u32 nsid , enum nvme_get_features_sel sel );

she returns void, meaning she does the work and hands you nothing back — the classic "i already did it, you're welcome" main character energy 👑

---

🦋 ARGUMENTS 🦋

• cmd — the passthru command you want her to fill in. that's the canvas, the blank canvas, the whole vibe 🎨
• nsid — the Namespace ID. which namespace are we talking about, bestie? this one. 📍
• sel — which type of attribute to return. peep enum nvme_get_features_sel for the full menu of choices, iykyk 🍓

---

🌸 DESCRIPTION 🌸

so what does she do? she initializes the passthru command buffer for the Get Features command, and she does it with the FID value set to NVME_FEAT_FID_RESV_PERSIST. literally that's it. that's the whole job. reservation persistence feature, requested, initialized, slayed 💅🔥

no hidden lore, no secret extra params — you hand her the buffer, the namespace ID, and the selector, and she sets the feature ID for you. iconic behaviour, tbh 🌈

---

🧚 reminder: this is an initialize function, so she's prepping the command buffer — not running it. the actual "go do the thing" part is somebody else's episode 👀

and that's the page!! this gem came out of the libnvme API manual, dated October 2026 — mwah, tysm for reading, go init some passthru commands, ily, bye 💖🎀🦋
