Some more words, regardless of in-tree "fs/xfs/libxfs",
you also claimed "Another goal is to share the same code between user
space and kernel space in order to provide one secure implementation."
for example in [1].
I wonder Rust kernel VFS abstraction is forcely used in your userspace
implementation, or (somewhat) your argument is still broken here.
