Like net_device gets redefined or typedefed in a bunch of drivers
striving for backward compatibility.

I wrote a little perl script to post-process the tags file to sort
duplicate entries that are "more important" to the top, where that means

    struct >> typedef >> union >> ... >> #define >> ...

So vim goes to the "real" definition of net_device first, before any of
the overridies in the drivers.

See http://www.osc.edu/~pw/index.html#tags for the script, and a
more complete set of ignores.
