Porting BTRFS to user space

Hello BTRFS developers,

I am requesting your opion.

I am planning to design and implement DFS version of BTRFS. Roughly it will be done by
1. Extending current DeviceID to NodeID:DeviceID to support multi-node, and
2. Implementing inter-node data and meta-data access over TCP.
Do you think it would be feasible?

For development, I would like to port the kernel code to user space. I could continue to run in user mode or be ported back to kernel space. But I don't know how can I start to porting the kernel code to user space. Is there anyone who can help?

Personally, my suggestion would be to start with a port to FUSE, and then start implementing your modifications off of that. That said, much of the code should already be available in userspace through libbtrfs, which is packaged with btrfs-progs.
