good job!

I'm not sure I understand you point, if an inode gets removed, then GETATTR or LOOKUP would fail as it should unless you're talking about open files. In the latter case the inode will get removed when the last open handle to the file is closed

I don't understand the comment about leaking memory, nfs file handles don't have to be persistent. Besides, how many FUSE filesystems implement FORGET? Anyway this is the reason I went with NFSv4. I started the project with NFS v3 but then discovered many limitations: being stateless, no named attributes, questionable locking support, etc. So Eventually I dropped it and re-implemented everything on NVSv4.

tcp ports are much more versatile, you can expose it to the outside world as opposed to unix sockets. Now exposing an nfs server to the outside can lead to interesting possibilities: for example you can implement a local fuse file system which can be mounted remotely through the NFS. It's highly not recommended at this moment because there's no authentication implemented

The author here. DriverKit is really a no-go. A while back I was asked to do a project based on DriverKit, it took me nowhere because of countless bugs and semi-implemented features, worse yet, it caused system crashes (and it was supposed to be stable).

There's new project that aims to deliver libfuse for mac without using kernel extensions. check it out.
