nvme_init_i...allocated_ns(9)

💖 nvme_init_identify_allocated_ns 💖

okay so bestie, this is a page from the libnvme API manual, and it's literally all about one tiny function that sets up a passthru command for the allocated Namespace ID list. it's giving "small but crucial", no cap 🎀

---

✨ NAME ✨

nvme_init_identify_allocated_ns — Initialize passthru command for allocated Namespace ID list

like, it preps the command buffer so you can ask a controller "hey which namespaces are actually allocated?" 💅

---

🌸 SYNOPSIS 🌸

void nvme_init_identify_allocated_ns (struct libnvme_passthru_cmd *cmd ,
__u32 nsid , struct nvme_id_ns *ns );

note the void — it returns nothing, it just does the thing and dips 🦋

---

🎀 ARGUMENTS 🎀

• cmd — Command data structure to initialize. this is your lil command vessel, and the function is gonna fill it in for you ✨
• nsid — Namespace to identify. which namespace are we looking at, bestie? 👀
• ns — User space destination address to transfer the data. this is where the data lands when it comes back home 🏠

---

🧚 DESCRIPTION 🧚

so like, what does it do? it initializes the passthru command buffer for the Identify command, with the CNS value NVME_IDENTIFY_CNS_ALLOCATED_NS. that's the whole vibe — it sets up the buffer, sets that CNS value, and hands it back to you ready to go 💜

---

ngl, it's a tiny function, but if you skip it your Identify command won't be pointing at the allocated Namespace ID list and you'll be sitting there like "why is nothing working 😭" — so just call it, okay?

---

that's the whole page, bestie — short and slay ✨ this was the libnvme API manual, dated October 2026. mwah, go initialize some commands 💅💖
