I can see the allure, but we have a long history here with fsxattr,
so I think it serves the users better to reference this history with
fsxattr64.

That, and also, avoid the churn of s/fileattr/file_kattr/
If you want to do this renaming, please do it in the same PR
because I don't like the idea of having both file_attr and fileattr
in the tree for an unknown period.

Thanks,
Amir.
