🦋 DESCRIPTION 🦋

So this does a low-level format, which is the fancy way of saying it sets the LBA data size and the metadata size. Cute, right? A little tune-up for how your namespace thinks about blocks.

⚠️ but bestie. listen. it may destroy data & metadata on the specified namespaces. like, gone gone. no take-backs, no undo, no "wait I needed that". this is not a drill, it's giving "did you back up first?" energy 💀

⭐ RETURN ⭐

Two possible outcomes, pick your fighter:

• the nvme command status, if a response was actually received (go check enum nvme_status_field for what those statuses are saying 👑)
• -1 otherwise, with errno set to explain the whole situation 🫶
