🌸 NAME 🌸

nvme_ns_rescan — kick off a controller rescan 🌀

🎀 SYNOPSIS 🎀

int nvme_ns_rescan (int fd );

🦋 ARGUMENTS 🦋

• fd — the file descriptor of your nvme device, bestie. that's the whole vibe 🌈

💖 DESCRIPTION 💖

okay listen. this one has a rule and the rule is only send it to controller handles, not to namespaces. like, it's literally right there. do not pass a namespace fd, queen, that's not the assignment 🙈

⭐ RETURN ⭐

• 0 — slay, a rescan was initiated ✨
• -1 — with errno set, otherwise 💀

no cap: if it comes back -1, go check errno. that's where the tea is ☕

and that's literally it, the whole page, short and iconic 👑
