Not really that bad.
My idea was to make a
struct kdirent {
struct dirent foo;
cookie stuff bar;
}
Filesystems would call vfs_read_dirent() with a struct kdirent and
depending on the userland/kernel flag in the uio vfs_read_dirent()
would copy either the entire kdirent or only the userspace dirent.

I'm generally in favour of people doing work so I don't have to but
in this particular case that was not the motivation :-)
(At least you can't prove anything!)
