The current calling conventions for ->follow_link() are already fairly
complex.
What we have is
1) you can return -error; then you must release nameidata yourself
and ->put_link() will _not_ be called.
2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0
3) you can do nd_set_link(nd, path) and return 0
4) you can return 0 (after having moved nameidata yourself)
jffs2 follow_link() is broken - it has an exit where it returns
-EIO and leaks nameidata.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
