🦋 puffs(4) — Pass-to-Userspace Framework File System 🦋

okay bestie, welcome to the puffs(4) page — it's a kernel interfaces manual situation, and yes, the manual name is right there in the title, periodt. 💅

🌸 NAME 🌸

puffs — Pass-to-Userspace Framework File System

✨ SYNOPSIS ✨

file-system PUFFS
pseudo-device putter

💖 DESCRIPTION 💖

puffs provides a framework for creating file systems as userspace servers. The way this works is: the in-kernel VFS attachment is controlled through a special device node, /dev/puffs. That's the whole vibe check right there. 🫶

If you're looking to implement file systems, you should use the system through the convenience library described in puffs(3). That's the move, bestie — no cap. ✨

💀 Termination 💀

A puffs file system can be unmounted regularly using umount(8). And listen — the file system will automatically be unmounted in case the userspace server is killed or the control file descriptor closed. So it cleans up after itself, iconic behavior honestly. 😭🔥
