* Renamed a few parameters of the FS module hooks:
  - *file in the attribute functions to *vnode
  - v to vnode
  - I could barely restrain myself from renaming the "_*" parameters. I
    understand this marks return parameters, but I'd prefer a nicer prefix
    or suffix (that doesn't makes you think this is a private/internal
    identifier) like "out", "ret", "return", "result", or something similar.

I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?
