Hi
Is there a feature on the linux v3 or v4 NFS server to allow a process to
intercept the NFS RPC requests for file operations (open, close, read, write
etc) and handle them in user space? If so, can these be handled
asynchronously?
Alternatively, if this is not possible, is this achievable through VFS
i.ehave a process create and register a file system through VFS and
export it
through NFS? Now when the server handles a client's file operation, it goes
through VFS and ends up with that vector registered by that process?
Thx,
MB

No. You could modify fuse to support nfsd, or you could write a
userspace NFS server (or modify an existing server).

Isn't it simpler (and potentially inefficient) to export the NFS mount
point as a FUSE filesystem?
