FWIW, I rather dislike this conversion and the DEFINE_SHOW_ATTRIBUTE()
approach in general. It makes it basically impossible to go from
ptdump_curusr to ptdump_open_curusr without opening up the macro and
reverse-engineering it.

My test is that for these macros to be sane, I need to be able to find
"ptdump_open_curusr" by grepping for "ptdump_curusr". This fails the test.

I don't think saving a few lines of code is worth the obfuscation.
